Mousetrap Car

thingiverse

I'm going to have to design a mousetrap car for my engineering class, so it seems only fitting that I upload the plans online. Take note of the two slots designed into the car - one mousetrap powers its movement while the other launches a nickel once the destination is reached. This calls for the use of three key parts: string, axles and multiple mousetraps. Building the Mousetrap Car Ensure model scale accuracy by making the necessary adjustments to unit size; I had to switch from mm to inches using Makerware due to limitations on my build plate. Should you require it, I can upload .x3g files set at 5% fill for extra structural integrity - the raft feature proves useful in supporting key areas like the chassis base, wheels and both arms. If necessary, swap out different pieces to accommodate a smaller or larger print job - a full-size Chassis base is suitable for bigger build plates, while a halved version will suffice on smaller ones. A simple yet effective way to assemble the vehicle is to glue each component in place; I opted to use JB weld to secure the pieces firmly together.
