Pepper grinder drive shaft

thingiverse

A replacement part for a commonly available pepper or salt grinder (France). The grinder is made of glass. Its knob connects to the square shaft by an acrylic piece that will easily shader. Poor design choice. This part replaces the original acrylic block with a more durable design. I bet the glass will crack before the part gets any sign of fatigue now. The clear glass body let you play with colors : I made the classic black & white for pepper & salt.
