Conical burr interface for Nuvita manual coffee grinder

This is a replacement part for the Nuvita manual coffee grinder.

This part allows the drive axle to interface with the ceramic conical burr. The stock interface (right side of picture, broken and in black) is fairly weak and seems to skimp on material as-a-whole. The printable replacement (left side of picture, printed in natural ABS) was designed using all the available space within the ceramic conical burr.
