Magister MMD08 Coffee Grinder Stepless mod

Extra hardware required for the crank: 

• M3 x 20mm screw to fix the crank body to the worm gear shaft, you can also use glue.
• M3 x 10mm screw for the crank handle.

This is not a hard mod since it mounts to the same holes the grinder already has, it can be reversed at any moment.
