Replacement part for coffee grinder

## Replacement part for manual coffee grinder My cheap chinese-made coffee grinder (like [this one](https://www.aliexpress.com/item/32796015340.html)) broke; upon inspection it turned out that the part that transfers torque to the rotating burr is made out of thin plastic, and is quite flimsy (black one in the picture). I'm surprised it lasted as long as it has. Instead of modeling the part as it was, I designed it from scratch to be more robust. The resulting piece will outlast the rest of the grinder :) OpenSCAD file included, should you need to make any changes.
