Fidget spinner where the outer ring should be able to press in 3/16" Steel BBs should hold about 30 bbs center bearing is for a 608 (22mm od)

Will likely need supports touching bed but should be ok to produce the outer ring with no supports in it so the bbs can move around.

** Edit ** I can see a few flaws in how this might print. ill check them out a bit more later and post and updated version once they are fixed. Also the fixed version wont need any supports.

Revised version is now available. This should be printed with the larger flange/ Diameter down and should require no supports.
