This Keychain Gearbox features two functioning gears that rotate effortlessly with a gear ratio of 1.5:1 (12:8). Additional ratios will be posted shortly. Applying a small amount of lube will further enhance its smooth operation. We crafted it to minimize waste, allowing it to print without the need for support material.
