It is time to bring the venerable mousetrap car races into the modern age with a 3D printed mousetrap car.
This product contains the files necessary to print and assemble a Mousetrap Powered Car.
The printed files uses CDs or DVDs for wheels. The car is so light it needs the wheels for weight. The wheel hubs are designed to fit snugly into a standard CD opening.
A pencil can be used for the extended armature, and a strong thread or string can be used for the axle system.
