Yo-Yo for use with a 22mm skate bearing

thingiverse

I used ABS at a 0.3 layer height and 40% honeycomb infill with supports, opting for PLA as an alternative that would likely yield acceptable results. The model requires rotation to lay flat, necessitating the printing of two units. I chose a higher infill rate to add weight to the outer sides. Since the STL file only contains one side, I printed two pieces and attached them together by gluing or screwing the center race of the 22mm bearing in place, allowing the outside to spin freely.
