3D Printing Projects 202204 – Walker Skis & BobBootSki

Bob needed some walker skis. I had printed some many times as the abrasiveness of the pavement and friction wear them out. I dug up the file and printed some that I had many times before.

This design was printed to fit some rubber boots that slipped over the walker leg pipes. The unit was held on by a screw, nut and washers.

Bob took these home only to realize that his system was slightly different. The pipe ends were a molded cup with a screw holding an insert for the internal diameter of the pipe. My first thought was to print some boots in Nylon that would adapt the the skis. I started that design project in Onshape sketching and revolving the shape without detailed dimensions. I called the file, BobBoot. When finished I thought, “why not just print the whole thing and use his inserts?” Here’s the result. Hidden is the fancy boss on the bottom of the cup that locks the insert from rotating and accepts a screw to hold it in place.

“BobBootSki”

I added detailed dimensions and developed the boss to receive the insert. When finished I thought, “might as well add the ski!” With a quick rectangle and ski profile I swept the ski attached to the boot. Now the device is called the “BobBootSki.”

Parts were printed in ABS on Cat’sPaw (FF Creator). 

3D Printing Projects 202102 – Ender 3 Enhancements

TPM Technologies Ender3 fan covers and nameplates for Build Your Own workshop.

Our Ender 3 club has developed a number of enhancements for the Ender 3 beyond the offset square.  The Makerspace at Cumberland Business Incubator sponsors a Build Your Own class for the Ender 3. Eleven embellishments are included in the class. Here is a shot of a few of them. The fan covers started with a monochrome stl downloaded from Thingiverse. The stl file was imported into TinkerCAD. Then, converted to two stl files by taking a thin slice at the start of the lettering to allow the letters to be printed in a different color. Using the dual extrusion wizard in Simplify3D the files were processed into one build file and printed on Killer, a Flashforge Creator Pro machine. The nameplates were developed in Solidworks and two stl files extracted to follow the same workflow for printing.

Parts were printed in ABS on Killer class (FlashForge Creator Pro) machines. 

3D Printing Projects 202011 – Smart Phone to eyepiece adapters

TPM Technologies Smart Phone to eyepiece adapters. Test fit on binoculars.

Buddy Bob wanted some smart phone adapters for a telescope. Searched on Thingiverse and found many to choose from. Here is a couple of the choices selected.  

 

TPM Technologies Test fit for smart phone.

Some parts were remixed. Thumbnut and Thumbscrew pieces were fit for 4mm Hex head screws. These were applied to the phone locking mechanism. A more traditional thumbscrew knob was used for the eyepiece clamp. The original eyepiece diameter was 1.35 inch and was redesigned for a 1.25 inch diameter using SolidWorks.  The phone clamps on the open ocular unit were modified to be even with the smart phone surface using TinkerCAD.

Parts were printed in ABS on Killer class (FlashForge Creator Pro) and Makerbot Replicator  and in PLA on Ender 3’s. 

3D Printing Projects 202012 – Model Mower for the Lawn Ranger

A client had a special mower that he wanted highlighted. His business name is the Lawn Ranger.

A1/8 scale Lone Ranger has a 1/8 scale mower to be a mascot for The Lawn Ranger business.

The mower was designed in SolidWorks and printed in ABS on a FlashForge Creator. Sizing was established by using the tire sizes at 1/8 scale.

3D Printing Projects 202003 – Mask Clips Print Farm Style

THE STORY

Healthcare workers ran across this article on Facebook and inquired about the possibility of printing them locally. Finding the file on Thingiverse and after a quick test print on “Groot” the go ahead was given for 150 copies. The nine Ender3’s were called into action printing 5-up at a time to crank out 200 in the space of a couple of days. PLA was used in multiple colors. A yardstick was recycled and 3D printed end pieces in ABS made it easy to keep track of production by counting the color bands. A single lime green strap marked the 100 position. 

The inspiring Facebook article and the resulting initial lot of 150.

THE REST OF THE STORY

After removing so many clips from both glass plates and polymer skins some embellishments were conceived. TinkerCAD to the rescue. A name was embossed as well as a little dent in the bottom surface for easy removal.The tweaks were then exported and re-sliced in Simplify3D.

Here’s a shot of the Ender3 “Printer Farm” in action.

3D Printing Projects 201801 – Dust Collection for Legacy CNC

Having an effective dust collection system for a CNC router keeps the area clean and chips don’t get a change to foul up the cutting. Pipe and snout pieces were designed in SolidWorks and printed in ABS. The primary nozzle has a T-slot where a flexible brush can be inserted. The system keeps the work surface tremendously clean. Parts were printed on FlashForge Creator and Creator Pro.

 

3D Printing Projects 201701 – Biki the Rubiks Cube Solving robot

Biki is a tweaked design based on O.T. Vinta’s Rubiks Cube solving robot. All constructed of 3D printed ABS minus some fasteners and motors. A significant change from the original was to make the legs in 3 pieces with print orientations to maximize the strength of the various parts. The carrying handle was also not part of the original design. The embossed embellishments were created in SolidWorks. Simplify3D was used to drive various build files for the FlashForge Creator and Rostock Max.

3D Printing Projects 201603 – Biscuit Gluing Brush

bobbiscutBob the woodworker has a special flexible brush for spreading glue but it couldn’t reach in the crack of a biscuit slot. We developed a two filament print using Tough Ink filament for the bristles and ABS for the handle. The bristles are about 1/8 inch wide and fit easily in the biscuit groove.The design was done using SolidWorks and Simplify3D makes the work flow of two headed printing streamlined. The part was printed on the FlashForge Creator.

3D Printing Projects 201602 – Dino Bank

ds dtA friend was interested in a Dinosaur bank. We found a Brontosaurus on Thingiverse. The body was hollowed out in Meshmixer and a coin slot was added. The unit was scaled and sliced with Simplify3D. This was a two tone version just to add some variety. The part was printed on the FlashForge Creator in ABS.

3D Printing Projects 201501 – HO scale wellcars and containers

The lineup of four, 5-gang well cars and containers all 3D printed.

TPM Technologies had the opportunity to present 3D printing applications to model railroaders at a regional convention. The application chosen was containers and wellcars. Every car and containers starting with the 4th car are 3D printed.

Why containers and well cars?

The design was developed in SolidWorks and the majority of the parts were printed on the FlashForge Creator, “Cat’s Paw”.

Here’s is a close up of some of the cars in the railroad club’s layout.
