After realizing how long it takes to hand grind coffee, I modeled this adapter to use a cordless screwdriver with the Javapresse manual coffee grinder. This adapts the hex socket to a pentagon socket.
Print horizontally to avoid vertical delamination. I use 100% infill, support angle at 60 degrees, and support density 20%.
