Project — Once a CONCEPT goes from ideas and CAD Drawings, Renderings, and images to Real World ‘Hands-on’ items in the Workshop it is a PROJECT.
I may also detail out past projects so I have a record of them. Some PROJECTS are quite simple such as helpful Workshop Tools and others much more advanced and take years to complete.

While installing the ARLO camera Rosie-Cat informed me there were little ants coming in the house which usually happens in the spring and in late summer.

Put out the 3D-Printed (Borax & Honey) Ant Bait Box each time …  They will take the Borax back to the nest and they will be gone in 24 hours … and we not see them again for several months.  Yay!! 🙂

Pam Marlen – Artist (1938-1997)

Art Studio Poster Explaining Pam Marlen’s Glass Bead Making Process

Today would be my mother’s 79th birthday, she passed away in 1997.

Pam Marlen ( Mary Pamela Smith) 1938-1997 Artist

I have very little of my Mother’s artwork, and if not for the kindness of my little brother sending me several items I would not have any.

As-well-as designing Passive Solar Houses, Gardens, and Landscaping – She also created amazing fused glass creations, pottery, glass beads, quilting, water colors, stained glass, and probably many other items I’m not remembering as I write this post.

She would even make the  unusual fun vests she would wear to events …

Back label on Pam Marlen’s ‘Buttons to Beads’ Self-Portrait

Much of my mother’s artwork was sold and anything left after her death was distributed amongst the family; therefore, the stunning Fused Glass pieces are owned by others, but I am very happy to have what might be one of my mother’s only artistic self-portraits.

Buttons to Beads Quilt with Glass Beads by Pam Marlen

Pam Marlen didn’t do anything normal, and if she was going to do a self-portrait of course it would be something unusual like combining Quilting & Glass Bead making to make the portrait of her making Glass Beads …

Paper that was pinned to Quilt – Houston National Quilt and Beads Showing

She also included herself playing with buttons as a child in the portrait …

Pam Marlen as Child Playing with Buttons

All of the Glass Beads attached to the quilt were made by Pam Marlen and they were sewn to the quilt using buttons on the back …

Back of Buttons to Beads Self-Portrait Quilt by Pam Marlen

My mother liked to save items that she didn’t feel were worth selling because there was an imperfection on those items… she didn’t save much but some items had imperfections she liked and would save them inside her studio, just for her own collection.

I’m not sure how many people knew about her ‘imperfection collection‘, but she and I talked about them once and it was fascinating how she liked something special about each one.

Fused Glass Examples in Background

A few years ago I found 2 new glass fusing/ceramic kilns for sale at a very good price and I purchased them … While my mother had taught me a little about fusing glass, I took a private ‘one-day’ class to refresh my memory.

Link to Post: Firebox-8 Kiln Height Extension

This Firebox-8 Kiln’s Temperature is Manually Controlled

Creating Fused Glass artwork is about predicting how it will look when finished semi-melting/fusing together … Thus, having no idea how to predict, I just overlapped interesting colors of broken glass into a pattern.

Cut & Broken Glass in Kiln before 1st Melting

After the first melting the instructor was very let down that the glass had cracked, but being my mother’s son I said, “Oh that makes it even more interesting, lets leave it and do the final melting to fuse it as is” …

Broken Slumped Glass that Broke and Re-Fused in Kiln

The final kiln firing softened the broken edges and created an interesting Fused Glass piece …  I placed it on my dresser and consider it the first of many of my own  ‘imperfection collection’ artwork pieces.

I imagine there will be many future Metal Castings to add to this collection 🙂

First Try and Glass Artwork on My Dresser

In addition to saving imperfect pieces, my mother also would create small pottery pieces that she could use to test out Pottery Glaze formulas …

Mini Glaze-Test Pottery Parts by Pam Marlen

It appears the items my little brother sent to me were part of a Green Glaze test and even these little items had her signature on the bottom.

While I only have test pottery pieces by my mother, I am proud to have those items because that is how I remember her – Always experimenting!!

Bottom of the Green Glaze
Formula Test Pottery by Pam Marlen

She signed all of her Pottery with a PM symbol  (Click images for larger view)

Pottery Signature on Test Glaze items by Pam Marlen

She had shelves of these small glaze-test pottery items in her studio …

A larger piece of pottery that was probably a Green Glaze-Test item

Mary Pamela Smith (Pam Marlen) was born in Tulsa, Oklahoma to E.R. and Mildred Smith on July 31, 1938.
She created most of her artwork in or near Great Falls, Montana.

This looks like a Bowl she used to test some Green Pottery Glaze

The pottery I remember the most as a child was a natural wash look as shown in the image below with hand-touched clay items added to pottery she had thrown on her potter’s wheel.

Natural Glaze with Clay Hard Artwork on Pottery

For years she would make pottery Christmas Ornaments and give them out to friends and family… Many times having us as kids help her.

Received photos of an items my mother made that I had not viewed before …

Hat made for Pat Erickson by Pam Marlen

Pat Erickson sent these photos to me of a hat my mother made for her …

If you enlarge the photo and look closely the bugs on the hat are glass beads.

Hat with Glass Bead Bugs made by Pam Marlen for Pat Erickson

Pat mentioned Pam Marlen made this hat for her birthday 🙂

Hat created by Pam Marlen with Painted leaves & Glass Bead Bugs

Thank You Pat for taking the time to send these photos!! 🙂

.   .   .

Pam Marlen had a stroke at age 58 in April of 1997 while giving a speech to get donations for the flood victims of the Grand Forks, North Dakota flood of 1997… passing away later in the year.

She lived an interesting life … and myself being a Star Trek fan it was almost surreal to come home to visit and learn her quilting group was asked to be extras in a movie directed by Leonard Nimoy… being very private director he would rarely talk to people on set; however, he would come over talk to my mother about quilting and other artistic items.

My mother met SPOCK …Too Cool!!

… MISS YOU MOM

3D Printed Chocolate Candy Molds

SolidWorks CAD Example of a SafeKids Chocolate Mold Shape

Just for fun several years ago, I showed Carma ( The Coordinator for SafeKids in Grand Forks, North Dakota ) how I could use their 2-Dimensional Logo and turn it into a 3D CAD model that could be 3D-Printed.

The SafeKids 2-D Logo I Turned into a 3-Dimensional Logo for 3D-Printing

Today, I am waiting on some parts to be delivered and decided to use the time to work on some 3D-Printed Chocolate Mold shapes for some friends of mine.

Randi and Carma’s wonderful daughter is getting married to about the coolest guy you’ll ever meet, and they asked if I could take some of their wedding designs and make them into 3-Dimensional CAD models that could be 3D-printed into shapes to make flexible food-grade silicon rubber chocolate molds.

Windsor and Matt the Groom to Be

The wedding chocolate designs are super secret until the wedding, but I thought this would be a good time to show the Chocolate Designs we made for the SafeKids Grand Forks 25th Anniversary Charity Event.

3D-Printed Candy Mold Designs I Made Years Ago

In a previous post, many years ago, I mentioned using 3D-Printing to make Candy molds:  ( Click Link to View Post )
3D-Printing & Plastic Part Molds – July 2013

3D-Printed Candy & Chocolate Silicone Rubber Mold Ideas

There is a helpful website if you wish to learn more about making Silicon Molds:

One of the Many Websites that Show How to Make Silicon Molds

2-Dimensional SafeKids Logo Designed by Correen for the 25th Year Event

Last year Carma (Mother of the Bride) asked if I would convert a 2-Dimensional SafeKids logo designed by Graphics Designer Correen into a CAD file for making 3D-Printed shapes to use for making chocolate molds for a charity event.

We also made chocolates for some of the event’s sponsors …

Several Different SafeKids SolidWorks Concept Chocolate Design Options

I sent several designs to Carma to review and she decided on the final design.

We Did the Entire Design Project 1600 Miles Between Locations

The process of making 3DP shapes for Candy molds is similar to making mold shapes for metal casting because one has to make sure there are draft angles allowing items to be pulled out of the molds after they cool.

For Candy & Chocolate molds non-toxic safe Food-Grade flexible silicon rubber is used ~ For Metal the 3D-Printed Shapes are pressed into Sand to create hollow areas to pour in molten metal.

To see some metal casting molds I made with SuperDave, click on this Link:
https://ctmprojectsblog.wordpress.com/2016/04/19/aluminum-cast-drill-press-knobs/

We Used SolidWorks Photo-Realistic Renderings to Choose Best Design

I emailed Carma SolidWorks renderings for her to view, and she would suggest design & size changes until we had a final design.

We Finished the Final Designs Several Months Before the Event

After SolidWorks CAD designs were done, I sent them to the 3D-Printing company Shapeways.com to be 3D-Printed.

SafeKids Logo 3D-Printed in High Res by Shapeways.com

I have a 3D-Printer; however, these 3D-printed mold shapes needed to be high-resolution so I sent the .STL 3DP files to Shapeways because they have very expensive 3D-Printers that can print extremely smooth parts.

One of the SafeKids Logo Shapes Used to Make Food Grade Silicon Molds

As usual, Shapeways.com did an outstanding job!!

3D Printed Chocolate Mold Shapes from Shapeways

Once the 3D-Printed shapes were done I tested some Food Grade Silicon and decided that I am not the person to be using sticky items and sent everything to Carma up in North Dakota to make the Silicone Rubber molds.

One of the Many Kits for Making Food Grade Silicone Rubber Molds

Carma, and the folks that helped her up in North Dakota, did a much better job than I could have ever done making the Food-Grade Silicon Chocolate molds.

SolidWorks Rendering to Show How the Chocolates Would Look

I’m not sure of the whole story, but as the event got closer there was an emergency Carma had to work on and her mother (Judy) stepped in saving the day by making hundreds of Chocolates using the silicon rubber molds.

Thank You Judy!!!

3DP Drywall Hole Repair

SolidWorks CAD Software Concept of a Drywall Patch

Many ways to do the same thing … and 3D-Printing added another way to patch a drywall hole left over after removing a Flat-Screen TV.

Removed an Old Flat-Screen TV from a Wall Exposing a Hole

In the past, I have patched many holes in walls using a plug cut from old drywall or purchased patching material from a hardware store.

Hole in the Wall after a Flat-Screen TV was Removed

Didn’t have any old leftover drywall material to patch the wall, so decided to draw up a 3D-Printed patch while I was relaxing watching TV in the evening.

So this is basically just for fun to see if I could create a patch with 3DP

Transparent View 3D-Printed Drywall Patch

The hole was 1.42″ in diameter where the Flat-Screen TV’s cords went through the wall to another room, so used SolidWorks CAD software to design a 3DP solution using Stainless Steel finishing nails.

Penny Taped Next to the Hole to Give Size Scale

Once the design was finished I 3D-Printed the two wall hole plug parts …

3D-Printed the Drywall Patch in 2 Parts

Tapped No.6-32 Threads in the outer plug’s holes for attaching inner plug …

Threaded Holes in the Outer Patch Part to Connect Inner 3DP Part

Tested No.6 screws to connect the two 3D-Printed Plug parts and all fit well.

Parts Used to Make the 3D-Printed Drywall Patch

Next tested placing in 1 nail at a time in the center of the plug and pushing them out as they would go into the sheet rock to secure the plug.

Used Stainless Steel Finishing Nails as the Locking Mechanism

The 3DP Wall Hole Plug can be mounted with 3 nails or 6 nails …

The 3DP Patch Locks Using 3 Nails but also can use as many as 6 Nails

Everything worked in the tests so next step was secure it inside the hole …

Supplies for Patching the Wall with Drywall Spackling

Rosie-Cat my SolidWorks Co-Designer fell asleep on the job so was on my own, luckily BKE said she would patch the hole if I would prep the wall.

My Co-Worker Rosie the Cat Sleeping on the Job

Just in case, I attached a string to a long screw in the hole plug so it would not fall inside the wall if I pushed it too far, but the fit was tight and it held very well in place about 0.05″ in from the wall to allow space for spackling the area several times for good coverage.

Attached a string to the 3DP Drywall Plug in case it fell inside the wall

Used all six of the 1″ stainless steel finishing nails about 1/2″ into the drywall.

The Design Allows for One Nail to be Pressed into Drywall at a Time

I could have pressed the nails up to 3/4″ into the drywall but 1/2″ in seemed to secure the plug very well and no need to go deeper and risk drywall cracking.

3D-Printed Patch in the Wall Ready to Have the Inner Plug Part Attached

Screwed on the inner rough finish 3DP part and everything fit well.

Randomly added a lot of Holes & Texture to the 3D-Printed Patch

With my part finished, BKE took over prepping the wall and finished it.

Spackle goes on Pink and turns White when it is Dry

The area will be sanded, textured, repainted, and artwork put on the wall.

3D-Printed Patch and Other Holes Covered with Drywall Spackle

When the artwork is mounted, I will update this post with a photo of it.

3D Printed Turret Vise/Fixture

Combining Metal Parts with 3D-Printed Parts

SolidWorks Concept Rendering of 3D-Printed Turret Vise

For years I have been combining 3D-Printed parts with Metal Fasteners :
Nuts, bolts, screws, washers, threaded rod, rivets, etc …

3D-Printed ‘Soft-Touch’ Vise for Clamping Delicate Parts

Recently I had the need for a Vise/Fixture with a very soft-touch to clamp delicate parts – and my metal vises were too strong – so decided to 3D-Print a ‘softer’ clamping fixture with Jaws on 2 sides.

GrabCAD Files ~ 3D Printed ‘Soft-Touch’ Vise/Fixture

3D-Printed Dovetail & Threaded Rod/Nut Connection

Actually, could have made it much simpler out of larger 3DP parts and not needed all the connections … but the point was to show Metal-to-3DP part connections, so I worked them into the design.

So please don’t waste your time 3D-Printing this fixture, because I’m only sharing it as a teaching CAD example to show Metal-to-3DP connections.

Vise will be used as a Robotic Fixture connected to Servos

This 2-Jaw Vise is actually a fixture I use for a very specific purpose, and it will not be strong enough for most purposes when used as a table vise.

I am connecting servos to it and wanted to make sure it could not clamp hard enough to crush my fingers without bending first – Hurts but doesn’t crush. 🤣

( Click on any of the images to see a Larger View )

Metal Parts Combined with 3D-Printed Parts

In addition, I like to design projects whereby parts from initial simple projects can later be used in more advanced project assemblies.

Two Vise Options that Use Many of the Same 3D-Printed Parts

Just for fun, I decided to design two Multi-Jaw Fixtures whereby many of the parts from the ‘Soft-Touch’ 2-Jaw can be used to create another rotating 5-Jaw Turret Fixture that could be mounted on my workshop table.

Top-View of a 3DP 5-Jaw Clamping Fixture Design Concept

I’m not going to 3D-Print the 5-Jaw Version because ( as designed ) it would not be strong enough for most uses, but it was fun to show how many little 3DP parts can designed to fit together using Metal-to-3DP part connections.

SolidWorks Design for a 2-Jaw 3D Printed Vise

Reusable 3DP parts are great way for individuals (new to 3D-Printing) to build confidence by printing just a few parts to make an initial project  … then later, they can use many of those early parts to build future projects.

Combining Metal with Other Materials

For decades, designers have combined together ‘dissimilar materials’using the materials they had available – to create objects for specific purposes.

Old Farm Machinery Combined Wood with Metal Parts

Years ago, while visiting a friend’s family farm, I noticed how vintage machinery was created using a combination of forged iron parts and wood.

Wood & Metal Vintage Machinery on a Friend’s Family Farm

This gave me the idea of using softer 3D-Printed materials combined with stronger metal fasteners & parts to create very durable items.

Carbon-Fiber 3D-Printed Speaker Box

SolidWorks CAD Concept for a 3D-Printed Carbon-Fiber Speaker Housing

Even if the 3D-Printing technology isn’t available yet for 3D-Printers to make items the size – and out of the materials wished for – I still continue to design items, preparing for future 3DP fabrication methods.

3D Printed Clone Part Designs

Section-View of 3D-Printed Vise connected with Metal Screws & Nuts

Learn By Reverse-Engineering 3D-Printed Assemblies

Instead of writing out in detail how I design each 3DP-to-Metal connection, decided to provide the CAD files for the 3D-Printed Vises on GrabCAD :

GrabCAD Files ~ 3D Printed Turret Vise/Fixture

Section-View of a 3D Printed Part with Threaded Metal Fasteners

You can download the SolidWorks CAD files, and/or .STL files, and review the parts to see the sizes & shapes I used to create 3DP-to-Metal Connections.

Transparent-View showing Straight and Angled Fastener Nut Slots

Specifically made the designs using many different 3DP connection methods.

Split-View of the the Slide Portion of the 2-Jaw Vise

In addition -Uploaded a 3DP Test Block to GrabCAD that you can print out to get the feel of the ‘fit-up’ dimensions used for many of my 3DP Projects :

GrabCAD Files ~ 3D Printed Fastener Test Block

.STL Files for the 3DP Hole Size ‘Test Block’ are on GrabCAD

The Test Block has all the different connections I use in my 3DP projects.

Printing the Metal-Fastener ‘Test Block’ on my AFINIA 3D Printer

Since I live in the United States, I used No.6-32 TPI screws and 1/4″-20 TPI threaded fasteners as the examples in the Test Block; however, the 3DP connection methods will work on all sizes, metric, etc.

Horizontal Vs. Vertical 3D-Printing of Fastener Part Holes

It does make a difference how you place items in your 3D-Printing software to print … Possibly in a future post I will go into greater detail … but if you want to see it for yourself just print the Test Block sitting vertical vs. horizontal on your 3D-Printer’s platform.  ( As shown in above image )

There are 2 Holes in the Test Block the Correct Size for Tapping Threads

You can also tap threads directly into your 3D-Printed parts, so I added 2 holes in the Test Block that are the correct size for tapping No.6-32TPI screws & 1/4″-20TPI threaded fasteners. ( Also the taper for flathead screws )

I Tap Threads directly into Many of my 3D-Printed Metal Casting Patterns

Dovetail joints are a great way to connect 3DP Parts ~ I used a few dovetail connections on the 2-Jaw 3D-Printed vise design.

Also used dovetail joint connections on a project for my friend Keith –

The Same 3DP Parts Used for Multiple Projects

Was talking with Brook (Founder/CEO of Printrbot) who has lots of cool ideas … and we discussed designing some projects whereby each 3DP project builds upon future projects … 3DP .STL part files work on many projects.

It’s about time to upgrade to a Printrbot with a large print platform!! 😜

Click Image to View Info about Printrbot 3D-Printers

For this project used the AFINIA 3D-Printer I have had for many years …

3D-Printing a Vise Part on the AFINIA 3D Printer

I’ve had a Multi-3DP .STL File Project Build concept for awhile, and have wanted to expand it so that when individuals, families, schools, and organizations buy a 3D-Printer they have numerous .STL file project options.

… So they aren’t just printing Yoda Heads* and Fidget Spinners 😜
( *Personal Note ~ Yoda head is VERY cool to print )

Vise Created with 3D-Printed Parts and Metal Threaded Fasteners

The goal is to have thousands of 3DP .STL file options to 3D-Print projects & experiments, whereby many of the 3DP parts already printed will work as parts in other future projects.

While the 3D Printed 2-Jaw Vise/Fixture does have many parts that can be used to make the 5-Jaw Turret Vise/Fixture – I would like future creative & scientific projects to have even more interchangeable parts.

Testing the 3DP 2-Jaw Vise on my Workshop Table

These 3DP Vise/Fixture designs are just examples to show the many different ways to connect 3D-Printed parts with metal items.

3D-Printed Vise Section Side-View Showing Threaded Metal Parts

Made this fixture to hold delicate items that I do not want to crush; thus, this design might not be strong enough as a table vise, and would suggest you create your own 3DP vise design that may work better for your projects.

Hopefully the Metal Fastener Connection information will help. 😀

3D Printed Household Items

For this post, I would like to show 3D-Printed Household items which I made on my own personal 3D printer as inspiration for others as to what YOU can make at home with a 3D-Printer.

Each item will have a link for more info and/or CAD & .STL files 🙂

ARLO Wireless Security Camera Mount

ARLO Security Camera 3D Printed Mount

Made this 3D Printed ceiling mount for a 100% wire-free, weatherproof, HD ARLO Security Camera that allows me to easily remove the camera to change the batteries every few months.

Even when the bottom screw is loosened the camera stays in place on the 3DP mount due to the camera’s back magnet still touching the mount’s back bolt, allowing me to grip it securely while standing on a ladder.

When I put the camera back on the 3DP mount after changing the batteries, it magnetically clicks in place between the sides holding the camera secure.  This allows me to release my hold on it so I can tighten the lower mounting screw.

Not everything created for the household is a complicated 3DP design as shown with these simple 3D Printed Cord Wraps that use Elastic Hair Ties …

3D-Printed Cord Wraps

3D Printed Cord Wraps Made with Hair Ties

It is very common to end up with only a few wraps of filament on a spool, not enough to make the next print, but too much to waste…  So I decided to make a few designs for items I could print when I was at the end of a roll.

Even did a Filament Weight Test to know exactly how much I could print.

Only Had 17 Wraps of Filament Left on the Spool

I use these ‘Hair Tie’ Cord Wraps on so many items that I am constantly having to print more … sometimes even when I am not at the end of a spool.

Close-Up of the 3D Printed Tab Used as Part of the Hair Tie Wraps

Spend so much time designing SolidWorks CAD items on the computer that, many years ago, I built a Computer Stand with a swing over monitor and switched my office to a LazyBoy chair ~ It is an incredibly comfortable work space!

LazyBoy Chair SolidWorks CAD Work Area

I set items I am measuring on top of the Computer Stand, so wanted to keep it clean and needed a good place to store my headphones within easy reach.

Used the Side Supporting All-Thread as a Place to Hang My HeadPhones

The logical solution was to use the all-thread side supports on my computer stand and design a hanger for the headphones to keep them out of the way.
( They don’t affect the Hard-drive *wink* )

3D Printed Hanger for Headphones on Side of Computer

When adding the photo above, I noticed the little 3D printed ring I made for my iPhone’s neck strap that keeps my clumsy hands from dropping my phone.

The strap ring is a good example how small of parts can be 3D-Printed 🙂

ANTS … ANTS … and More ANTS!!!

Sometimes the 3D Printer can make items very quickly that are needed in unusual shapes which would be hard to make any other way …

Like many homes we had a mini-ant summer invasion … and by mini I mean the size of the ants … the invasion was massive … Ants everywhere so we needed a solution quickly … Called the exterminator but they would not guarantee they could get rid of mini-ants … So had to come up with a solution of our own.

Borax and Honey Ant Bait Box Created with 3D Printer

The solution was using a Borax & Honey Ant bait mixture that the ants would take back to their nest and kill future ants from coming into the house.

Also needed a way to lure the ants to the bait without pets getting to the honey … Something low-profile that could be placed in areas pets can not reach.

Ant Borax & Honey Bait Pyramid created with SolidWorks CAD

It only took about 15 minutes to draw up this ANT BAIT PYRAMID in SolidWorks CAD Software and 3D Print several for around the house.
.STL 3DP files can be found on GrabCAD:
https://grabcad.com/library/ant-bait-pyramid-3d-printed-1

Within 24 hours we did not see another ant for the rest of the year, and each early summer we get the same Ant invasion; however, every year it is gone within 24 hours using these Ant Bait Boxes.

Turtlebutt the Amazing Adopted Desert Tortoise

We have a Desert Tortoise who is part of the Nevada Tortoise Adoption Program whereby Desert Tortoises that are injured, or born in captivity, must be hosted by volunteers in their backyards.

Turtlebutt is a good sort, he never bites people, very friendly, eats better organic food than we do … and most of all he likes to motor around the backyard somewhat like a bulldozer on legs.

Turtlebutt Giving the Eyeball Look with Food Stuck to his Face

He has grown considerably over the years causing an issue with the Patio bench he likes to walk under … He is a straight-line walking kind of guy, so we had to come up with a solution to raise the bench out of his way so he didn’t keep dragging it across the patio … even though seemed to enjoy moving it each day.

SIMPLE HOUSEHOLD PROJECTS …

I mention a lot that it is the simple things that make a 3D printer helpful …

We had a Window Cleaning Squeegee and the perfect place to hang it in the kitchen pantry but didn’t have the perfect hanger.

Once again … The Solution was to 3D Print a Hanger 🙂

Happy New Year 3D Printed Swizzle Stick

We have an elderly cat that came to live with us many years ago when she was 10 years old … and now at 18 she likes to sleep on my lap when I work on SolidWorks CAD drawings in my LazyBoy Computer Chair.

There was no place to put my keyboard without disturbing her sleep, so quickly 3D-Printed a keyboard mount that connected to my monitor and now Rosie-Cat gets to sleep whenever she wishes.

Last summer some friends invited me to a 4th of July event ~ I sent mini SG Gibson guitar models as a thank you since they are fans of Gibson Guitars.

I wanted a custom mini-stand, so designed & 3D Printed this version …

Lots of Uses for a Household 3D-Printer!!

3D-Printing 4 More Rubber Band Hooks for Under the Kitchen Sink Drawer

I was intimidated the first time I used my 3D-Printer; however, now it is just another tool to make things … and the best part is once you press the start button you can walk away and work on other items (or go to bed) and come back later and the 3D Printed item is finished.  Yay!! 🙂

3D-Printers may seem like they take a long time to print items, but if you are doing something else during that time the 3D-Printer is making your part, then really it is like getting 2 items done at the same time.

I Enjoy Helping Others with their Just-for-Fun 3D Printing Designs

If you get a new 3D-Printer and find yourself stuck on how to draw a household solution … Drop me a comment on here, or @MetalDesigner on Twitter, and we can see what we can come up with for a solution just for the fun of it.

3D Printed BBQ Door Hinges

We have the best neighbors and like to exchange help on household projects.

Our Neighbor’s Finished BBQ Area Project

We needed some concrete work done on our pool & wall, and our neighbor was building a backyard BBQ area and needed Stainless Steel Doors.
( He owns a Custom Concrete & Stone Business )

BBQ Area BEFORE Stone was Added to Cover Concrete Block Structure

He showed me the concrete block BBQ structure so I could measure the openings that required two single doors and one set of double doors.

Small Opening that Needed a Stainless Steel Door

The plan was to cover the BBQ concrete block with Stone approximately 1.5″ thick; therefore, I needed to come up with a design to hold the Stainless Steel doors out far enough to match the thickness of the stone.

Outer Covering of Stone Being Installed

Decided to use stainless angle to create frames and use 3DP for hinge parts …

SolidWorks CAD Model for One of the Stainless Steel Door Units

Created the BBQ Door designs using SolidWorks CAD Software …

Testing in SolidWorks How Much the Door Would be Able to Open

Matched the top of the handles the same distance from the top of doors …

All 4 of the Stainless Steel Doors I Designed for My Neighbor’s BBQ Area

Once I had the doors figured out … Made a quick BBQ area concept drawing.

Made a SolidWorks CAD Concept Drawing of the BBQ Area

Showed the BBQ area concept designs to our neighbor and he liked them …

Next step was to refine the Sheet Metal bends and hole locations using the ‘Sheet Metal’ feature which is included with SolidWorks CAD Software.

Stainless Door Drawn with SolidWorks Sheet Metal Feature

Created Sheet Metal Flat-Patterns to make sure the Stainless Steel Fabrication shop would be able to Cut the doors with a CNC Laser or shear.

The SolidWorks Sheet Metal Flat-Pattern Used to Create the .DXF file

After the designs were given to McClure Stainless – Metal Fabricators in Las Vegas – I was then able to concentrate on the 3DP Hinge units.

Transparent View Showing the 3D-Printed Hinge Concept

Came up with a design that used a combination of 3D Printed ABS and Stainless Steel fasteners ( Nuts, Bolts, Screws ) …

Top Section View showing the Hinge Pin Unit and the Stainless Door

The BBQ unit required a 1/8″ gap around the doors for air flow, so I used a pin hinge and was able to test the turning diameter in SolidWorks.

Testing the Door’s Edge Opening Clearance inside the Frame

I knew the door’s sheet metal bend radius when received the finished Stainless doors from McClure Stainless, so adjusted my SolidWorks bends to match the bend radius of McClure’s press brake’s tooling.

BTW ~ McClure Stainless, LLC made the doors very fast & great workmanship!!

Was also able to test the maximum angle the doors could be opened.

3D Printed Hinge Pin Mount Parts and Lathe Screw Cutting Fixture

Part of the Hinge Pin design required turning (cutting) off some of the thread on a stainless fastener to create the hinge pin end.

Making a Hinge Pin from a Stainless Steel Screw on My Metal Lathe

Made a quick fixture to hold the stainless screws in my Metal Lathe’s jaws.

Brenda Picked Out Door Handles to Match the BBQ’s Curved Handle

Purchased the Door handles from LOWES to match the BBQ’s main handle.

3D Printed Hole Drilling Guides for Door Edges

Decide it would be faster & easier to drill the holes myself, and I wanted all the doors to have the same hole locations, so I 3D-Printed a punch guide for marking where to drill the holes in the bottom and top of the doors.

3D Printed Handle Screw Spacers to Adjust for Thin Sheet Metal

The handles purchased from LOWES were designed for thicker wood, so I 3D-Printed spacers for inside the doors to allow the screws to compress against the 0.050″ thick stainless steel sheet metal.

SolidWorks Screen-Capture Showing Magnetic Door Catch Design

Also 3D Printed mounts to hold Ferritic Stainless Steel washers used in combination with Rare Earth Magnets pressed into 3D printed door catches screwed to the outer door frames.

3D-Printed Hinge Pin Mount Hidden Inside the Door

Mounted the hinge pin units after I finished drilling all the holes …

Stainless Screw Hinge Pin in BBQ Door

I made the holes slightly larger than the hinge pin in case I needed to re-3D Print the inner mounts to adjust door alignment inside the frames.

3D Printed Spacers on Top and Bottom of Doors

Came up with an Upper & Lower spacer design that provided maximum coverage but also can not be viewed when door is opened and closed.

3D Printer Software Showing a Multi-Print of 16 Spacers

When 3D Printing little parts I like to print them in large groups to allow the filament to cool on each part before starting the next print layer.

It took over an hour to 3D Print the 16 spacers; however, once started I could work on other items out in the workshop during that time.

Notes to Myself So I Would Not Drill Holes in the Wrong Location

Still use paper drawings in my workshop, but find I am using digital .PDF drawings and eDrawings on the iPad more and more as time goes on.

Using Paper Drawings as well as eDrawings Viewed on My iPad in Shop

Used the Miller Dynasty TIG welding machine in my workshop to make the door frames from 1.5″ x 0.125″ Stainless Steel angle …

Stainless Steel Door Frames Ready to be Mounted onto Concrete Blocks

Drilled lots of extra holes in the Stainless Steel door frames to allow for good anchor bolt/screw mounting locations on the concrete block.

Stainless Steel BBQ Door Frames

After the door frames were in place our neighbor finished the stonework …

Neighbor very pleased with the results & I feel the doors look nice with stone.

In the photo below you can see one of the magnetic Ferritic Stainless catches.

Noticed I Forgot to Wipe off Finger Smudges Before Taking Photos

Below is one of the 3DP Hinge Pin Units with the Top Cover removed.

As a bonus I got to be part of the first BBQ Cooking test!! 😜  Yum!!

As with many of my 3D Printing projects the CAD files are on GrabCAD.com

Also made a quick SolidWorks Tutorial Video showing how I used the ‘Mirror’ part feature to create mirror-image ‘clones’ of the 3D Printed (ABS) Hinge Pin part inserted into the top & bottom of the Stainless Steel BBQ doors.

Now that I know the 3D Printed ABS Hinge Pin units work with the Stainless BBQ doors,  I will probably reprint them in metal at a later date just for the fun of it.
