-Hardware:
-1x Bearing (12mm ID, 24mm OD, 6mm Depth)
-1x Magnet (5mm diameter, 2mm depth)
-Print outer part with PETG. Inner gear can be any material.
-Magnet may need a drop of CA glue to prevent it coming out with the hex bit
-Absolutely cranking it will cause the petg pins to buckle. Your mileage may vary based on your PETG. (be careful with it)![]()
