Per a request, here's a Spiderman fidget spinner that I came up with. This spinner uses (3) 1/2" ball bearings and (1) 608 bearing. This spinner is about 4" in diameter overall.
EDIT: I uploaded a model that needs one 608 skateboard bearing.
EDIT 2: I uploaded a model that uses (3) 5/16" nuts and one 608 skateboard bearing.
