Toothless 3-part Grinder

thingiverse

This is my take on the toothless grinder that has become popular on thingiverse. It consists of three parts, has a compartment for the ground up herbs to fall into, the teeth are stepped in depth for less things to get stuck. The toothless surfaces are oppositely positioned for optimised shearing motion. I used the magnets from the box of Gizeh rolling papers, they are 5 mm in diameter and 1.5 mm in depth. They're glued in for optimal user experience. Side note: The parts in the picture are the last prototype iteration, hence they were printed in around two hours. Pictures of a 20+ hour version will be coming soon, as well as customizable 3D-files, so you can fit your magnets.
