CLIPGEAR is an infinitely expandable, modular gear system. Snap the bases together, clip the gears on, and build your own mechanical creations - or simply use it as a satisfying fidget!
The system is designed to be simple, lightweight, and endlessly expandable. It supports 1:2 and 2:1 gear ratios, allowing you to trade speed for torque, or torque for speed. It also includes a variety of gears and special parts, including gears with a wheel and a fan, with more possibilities to come.
Gear Sizes & Files
Gears are available in 16, 24, and 32 teeth. Files are named Gear X-Y, where:
X = bottom gear
Y = top gear
For example, Gear 16-32 contains a 16-tooth bottom gear and a 32-tooth top gear.
Printing
No supports required
0.20 mm layer height recommended
PLA or PETG both work well. PETG on the base makes the connections easier
