one-way clutch bearing
thingiverse
One way clutch bearing for a rotor. 107 mm diameter with 8 bearing wheels. I added a new one with 5 bearing wheels. the clearance was to much in the first one. Clearance in this one is .55 mm. the smaller holes are for 15 mm neodymium magnets and the bigger holes are for pennies to add some weight.
