Ball Bearing Fidget Spinner (Print In Place)

thingiverse

Simple print-in-place fidget spinner! Print with no supports, no raft. After printing, spin the inner ring and the outer ring in opposite direction to break any connections that may have formed on the first layer. For the lowest friction, ensure all balls are freely moving. Even one stuck ball will significantly reduce performance. For a cool look, try switching filaments mid-print! If you make one of these, please post a make! I'd love to see how your printer handles the geometry.
