Momentum Fidget Spinner

Post-Printing

Uses 10mm diameter rare earth magnets, which come in a variety of thicknesses - The thinner magnets allow for more configuration options, using more magnets should result in transitioning at higher speeds.

Superlube oil* or similar - I usually disassemble it after printing and a few minutes of break-in, then add one drop of superlube into each of the pivot points.
