About this 3D model
This fidget keyring is a simple design using a 3 gear chain to do nothing but entertain its user. Turn the small gear and watch the other gears turn! Requires 3x 10-12mm m3 bolts and 3x m3 nuts. Revised Base & Top - moved both 30T Gears 0.5mm further from the 15T gear for easier spin. Revised both gears - bored to 5.5mm for extra clearance / easier spin.
