Description

This adapter sits right on top of the normally assembled Mokalov coffee grinder so the crank can be turned using a power tool with a hexagonal bit rather than by hand.

A lot of force is exerted on a very small surface, so most common printing materials like PLA or PETG break before a full load of coffee beans has been ground. For a successful print, I used:

  • PA6-GF (glass-fiber reinforced Nylon) filament.
  • Brim to counter warping.
  • Sufficient infill ratio to make sure the top portion where the adapter interfaces with the drill bit is solid.
