About this model

A very simple mouse trap car designed to be press-fit together with 1/4" dowel rods. Most parts were made with PLA (green in photos), and TPU for the rear wheel treads and front wheel axle caps. The TPU treads could likely be replaced with rubber bands to provide traction. The front axle caps keep the front wheel center and could be replaced with tape, a screw or something to keep the axle from sliding in / out. While the trap mounts set the car's width, you can experiment with the car and arm lengths. A loop in the arm string is hooked onto a small screw in the rear axle to allow for winding.
