Inspired by a 1920s design, I have crafted this ingenious device in the form of a credit card
Select the “no bearing” print profile if you lack bearings For optimal performance and increased speed, two 625ZZ ball bearings (EA016 Maker’s Supply) are recommended (many makers already possess these!), along with a ballpoint pen spring
For frictionless rotation, the bearings should be immersed in a degreasing solution and subsequently lubricated with WD-40
To achieve the carbon fiber effect, utilize the Fiber Carbon plate (as shown in the photographs)
Should you require wheels indicating more than six options, please inform me, and I will tailor a design to your specifications For instance, one wheel could display eight numerals, while the other could show twenty
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!
Have an amazing project to share? The Electronics Show and Tell is every Wednesday at 7:30pm ET! To join, head over to YouTube and check out the show’s live chat and our Discord!
