Gravity Car CD Wheels

thingiverse

This is a specialized wheel hub engineered specifically for retrofitting a standard compact disc as a wheel on a gravity-powered vehicle. Designed to work seamlessly with a number 8 wood screw, the hub utilizes a clever circular friction-fit clip to securely hold the CD in place. To make installation a breeze, a brass insert is incorporated into the jig, allowing for precise drilling of a perpendicular one-eighth inch hole that perfectly accommodates the #8 wood screws.
