Had some washers and a 608 skate bearing and I thought I would do the only reasonable thing... make a fidget spinner!

Stop the print before it prints the top retainers, insert your washers, and then finish the print. They will be held in nicely FOREVER.

Washers I used are about 32 mm (1.25 in) diameter and about 1.5 mm (0.05 in) thick. Use two per slot for a total of 6Washers (the name.. get it?)
