Description:
This Gearbox Keychain has two working gears. They spin smoothly and have a gear ratio of 1.5:1 (12:8). Other ratios will be uploaded soon! Use a little lube to make it run even smoother! As always, we don’t like wasting material, so we designed it in a way that you won’t need any support material.3D Print this one and
