You can spin just gears, or you can spin whole thing and gears will spin with it. Bearing hole tolerance is +0.2mm, don't expect long spin times, especially if you're using low quality gears.

If people are interested I'll clean and release Fusion 360 file, meanwhile, if you want different bearing holes, or bevel-spur version feel free to ask, I'll make and release it.

-all 608 bearing is impossible
-I tried to utilize airsoft bearings as bearings instead of spacers, they have much higher friction than 608 or 606.

-added dual version

-[22.07.2017] added v2 dual version with experimental top to bottom snapping mechanism

30% is enough, probably can go lower


push airsoft bearings into fidget bearing, shim like usual, or just push them closer.

Materials Needed

2x 606, 6x 608 bearings, 6x 8mm airsoft bearings,

2x 6mm low quality bushing, you may need glue to kill it(or you can try it with "spacer buttons")

V2/V3 3x spur gears and 1x sector gear OR 3xsector and one spur. I highly suggest to use identical or at least as similar as possible.
