Batman Fidget Spinner

Uses 11-4,5mm BB's for the bearing. you can press them in with a pair of channel locks. However it is much easier to pause the print about 75%-80% through and place them in. It spins better too. The weights are M8 hex nuts you can glue them in or heat and press them in the slot.
