Summary

Per a request, here's a Gears of War Cog fidget spinner that I came up with. This spinner uses (8) 1/4" ball bearings and (1) 608 skateboard bearing. This spinner is about 3-3/8" in diameter overall.

I would heat up the print and ball bearing with warm water and the bearings will slip in. I haven't tried printing this yet, but the balls should be very tight to snap in.
