Magnetic Detent Fidget Coin
A compact everyday-carry (EDC) fidget coin built around a simple idea: as the two halves rotate against each other, embedded magnets snap past one another and create clean, repeatable detents — a soft, clicky haptic feedback you can feel.
Bill of materials
Magnets: ⌀ 6 × 3 mm, at least 6 magnets necessary, up to 12 possible
1× 608 ball bearing (608-2RS, often called skateboard bearing)
Screws: M3x10 Countersunk
Print settings
Material: PLA / PETG
Layer height: 0.15 mm
Infill: 25 %
Supports: Required (only on the underside for the 608 bearing seat)
Print orientation
Print both halves with the decorative face up. The magnet pockets and bearing seat are on the underside. The bearing seat needs support.
Assembly
Press fit the magnets into the pockets (mind the polarity — all same orientation for even detents).
Seat the 608 bearing into the rotor half.
Join the halves and secure with the central screw.
Tip: Don't overtighten the central screw — just snug enough for a smooth, free spin.
