3D Printable Burr Coffee Grinder

A 99% 3D Printable Burr Coffee Grinder Designed to fit on top of a 8cm rimmed glass jar for catching the ground beans. (I used a old salsa jar). Only part thats not 3D printed in the spindle which is a standard bolt form home depot, 2 nuts and a washer for managing the tension on the burr.

Test printed on the PrintrBot Jr in PLA and unfortunately I dropped mine so the jar screw part is missing in the pictures.
