Fidget spinner for small children 608ZZ remix
Cut a hole for a standard 22mm 608ZZ bearing, it will not sit flush so a raised cap will be needed
13mm M8 bolt per original design but needs to be 13mm or less for flush fit or if you want to use the bolt as a "set screw" to lock in the bearing then just a little over 13 will be fine
I printed mine with 3 shells, 100% infill (its a small print so it won't use much plastic)
Very small so little kids can use it easily
-edit-06/11/2017 created a M8 threaded rod (standard pitch) and a 5/16" UNC threaded rod and placed in the holes (I don't have a tap set and was unable to force screwing in the bolt on the one w/o threads) [untested as of yet] tested...did something wrong...the threads are not round..correcting
