Spinner Bearing substitute

thingiverse

[Edit: added smoothing and balls as well as bolts and more sizes] You might want to replace the outer bearings in your fidget spinner with bolts. Some Bolts are heavier and give a longer run time. Also added spheres if you have them instead. This customiser allows you to select M10,12,14, and M8, M6 sized bolts or manually enter a bolt's size (in mm) for whatever you have lying around. It also allows you to use 4, 6 or 8 sided bolts, so you have more choices. (And spheres if you have oversized ball bearing spheres to use instead.) The standard 608 skate bearing is 22 mm across but the variable is exposed in case you want to change it.
