We've got some requests to make a bigger version of the gearbox keychain so we did.
This Gear Keychain XL has two working gears. They spin smoothly and have a gear ratio of 1.8:1 (18:10). 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.
