Fidget Spinner - Model 2

This is a fidget spinner I designed to work with standard 608 ball bearings, that fits almost any hand. I tested it using a 3D-printed bearing, but it is also designed to work with metal bearings; however, I have not tested with them. The caps for the bearings have multiple stem sizes, as every bearing is slightly different and will need a different size. I found the 6.25mm one works best with the 3D-printed bearings I used, and I recommend you try that one first.
