This is a handy little garlic press roller thing for the kitchen, easy to clean and destroys garlic easily with a push/roll of your hand-palm.

Make sure that the shell thickness is sufficient in Cura, I used 2mm with a 50% infill, which created a super strong object. And use PLA, not ABS as it'll be touching your food AND you'll need the hardness of PLA. You can print this standing straight up (at its tallest), without any support.

The roller in the picture is ideal if you have small hands, if your hands are bigger, just pick a larger model from the Sketchup file or scale it in Cura yourself.
