This is a fun fidget measuring 40mm square. The "ball" is printed inside of the cube the cube prints, encapsulating it. This has been a fun fidget, and I find myself messing with it at home and at work.

Supports are not needed. However, if your printer is not tuned well for bridging, you may want to add supports.

I printed at 0.2 layer height, with PLA, no supports, no brim, no raft. 3 walls, top and bottom layers, 15% infill.
