I stumbled across a 3D-printed magnetic slider toy and was intrigued — but also a little frustrated. The design felt a bit missing, the tolerances were off, and it didn’t quite “click” for me. So I decided to design my own version from scratch.
Introducing: Super Swivel Fidgets
These magnetic fidgets use 6x2mm magnets to create a light-switch-like snap as the slider glides around the base. It’s incredibly satisfying — and surprisingly addictive.
After dozens of prototypes (and sacrificing way too many magnets), I dialed in the right tolerances, ergonomics, and sound/feel balance. If you're into functional prints and fun ones, this hits both.
Key Features
- Tuned for precise friction-fit with 6x2mm magnets
- Fit Check plate so you can dial in X-Y Hole Compensation before committing
- Thumb-friendly, beveled slider shape
- Textured sides for better grip
- Dual-color print support without filament waste
Pro tip Adjust X-Y Hole Compensation by ±0.025mm increments to get a perfect press-fit if needed.
This was a surprisingly fun from a modeling and print-optimization perspective — and now I keep one of these on my desk.

Would love feedback from this crew!
