SpinSpinSpin, the BEARING-LESS Fidget Spinner

Summary Update: New Spinner! Spinspinspin G1 CLASSIC edition. ~A LONG while back when I printed the first prototypes of the sss G1, I designed them with text on the side to make it easier to identify them. So, I put the model number on two sides of the spinner and just for fun made it in two colors. The story is that little fidget spinners are actually a lot of fun, but they're often overpriced or require parts most people don't have handy like bearings. I started thinking, "Are bearings truly necessary?" This thing challenges that argument by being designed to print altogether in one part and being super simple to make! The steepest overhangs within the designs are only about 45 degrees so any printer can make these spinners. These fidget spinners were designed by me, and they consist of two parts: the inner and outer piece. The outer piece has a sharp corner around the inside edges of the circle, and the inner piece has slightly smaller grooves that are printed in place between the corners and spin freely without bearings or lube. Although, you can add lube for longer spin times if you want. As you may notice, these spinners are slightly smaller than other spinners but despite their size they're a lot of fun and kill boredom with ease. Their unique size is just one special characteristic that makes them stand out. ~MSR -Make. Share. Repeat. If any of you can make a spinner it would mean the world to me if you could submit your print and include your opinion. Anything helps improve this thing! -Matthew Print Settings Printer Brand: Robo 3D Printer: R1 ABS + PLA Model Resolution: .2 Infill: 20-100% Notes: Any resolution works, although thinner is better. No support is needed. Post-Printing How to make the spinner in three easy steps. Click Print. Pull off printer and voila! You're done. It will spin right away. Another thing you could do is add a tiny bit of sand between the moving parts to improve spin times after using it for a little while. This is completely unnecessary, though, and it spins fine without any adjustments. I originally designed the spinners in TinkerCAD BETA, and the new CLASSIC edition is a redesign from 123D. It's not too different from the ordinary G1.
