This fidget spinner works perfectly with 22mm bearings. Print with any infill amount, but I find that the more infill, the longer and better it spins. I printed using a Cetus3D Printer, but it will work with any printer. Use a raft and no supports are needed. Please don't sell this design.
Anything will work. I find the heavier it is the better it spins
After printing, remove the raft and insert bearings. If it is too tight, you can shave some material down with a knife.
I designed this with Fusion 360 using simple geometric techniques.
