Best printable grinder design out there. Nice job. I printed mine with PETG instead of ABS considering PETG is just as strong, but FDA approved/Food safe.

Also, for the bottom grinder part, the outer rim of teeth nudge up against the inside walls in a way that herb gets stuck between quite often. It bothered me enough to edit it and make the outer teeth connect to inside wall.

good morning, and printed all parties and three of gear planet and can not get sun gear fit in any way, you could say me where I could be my problem, because they are many hours of printing and it does not work at all and I I would like to use it because I like it

Tight tolerances are required to have sturdy functional parts. If your

machine is incapable of holding these tolerances, i suggest you look into

why, because the positional tolerance of a standard reprap is 0.10mm

(toolhead placement repeatability). None of the fitment tolerances are

beyond the capability of a well calibrated machine.
