Rough-texture Gyro Fidget Spinner

Something to do with your hands during a long call or a slow meeting. A round disc spins inside a ring, and the rim has a rough, pebbly texture that feels good under your thumb. Change the diameter or the ring width to suit your grip.

Turn on elephant-foot compensation, print slowly, and twist the rings gently to free them.

Good to know

  • Print a test first: the running gap is 0.4 mm and you can tune it with the Running gap slider (try 0.3 to 0.5). Friction and free spinning are untested.
  • The preview only checked part of the motion, because the check ran out of time, and the core spin wasn't checked at all. My own 30° rotation checks passed.
  • The pit texture is shallow (about 0.7 mm), so it feels rough but not sharp.
