Skull & Crossbones Fidget Spinner

Fidget Spinner body with a 22m (width), 7mm (height)  opening for a single bearing. Skull caps for a 22m (width) bearing, 7mm (height) and 8mm inner centre (width)

1. Print bearing caps, to check if it's a good fit for your fingers. Make sure to orient it correctly before printing, otherwise it'll be distorted.
2. Print the body.
3. Push in bearing once printed (It'll be a tough fit) through the body
4. Push in the bearing caps, so that it's aligned equally through  the centre in the bearing itself. 

All bodies can be printed separately for different filament colours.  In my opinion, it looks best with the two caps in a different colour than the body.  It has a light feel and balances well. Maybe try remixing it to accommodate four bearings on each side.
