I made a goal of designing a functional, fully 3D-printed caster that can swivel and lock the wheel. The wheel diameter is 4″ so it’s quite large. Although it actually functions pretty well, it won’t be able to roll under much load. I did try it out by mounting 4 of these to a table which I had my Ryobi planer mounted to (pretty heavy) and they held up in static load but due to the soft TPU tire, they couldn’t roll very well with that much load and ended up breaking. The locking mechanism requires that the tire be soft but maybe someday I’ll improve the design. For now, I wanted to get this out there. Maybe it will inspire someone to build off of it and make it better or maybe someone will find it useful for lighter loads.
Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!
Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
