Per a request, here's a Transformer fidget spinner that I came up with. This spinner uses (3) 5/16" nuts and one 608 bearing. This spinner is only about 3-1/2" in diameter overall.
I would heat up the print and ball bearing with warm water and the bearings will slip in.
I'll upload a picture when I print one.
