I know this build is a little off category here at OB, but I wanted to share it with the community (as well as other coffee lovers) and show however vast the possibilities are when OB hardware is involved. This is a powered stand intended to operate a manual coffee grinder. It is compact, light, portable and uses simple drive components (B&D Cordless Screwdriver). I will post two version, V-1 (Beginner skill level ) and V-2 (Intermediate skill level). Both accomplish the same results.

Stronger frame for Prusa i3 MK2(s), MK2.5 and MK3 3D printer

This is the largest printer I have found. It is also the cheapest. The reason is that it is run by hand, without computer or motors or electronics. Put an object on one side and move the 3d pen while tracing the object. Move the z dimension by turning the crank on the lab jack to move the printed copy down a notch. Be creative!
