This rubber band-powered vehicle is a fantastic project an elementary student could undertake in school. The assignment prompt might read: "Design and build a car powered solely by one rubber band that can travel a set distance after being pulled tight and released. " Print settings are as follows: rafts will not be used, supports will also not be required, a resolution of 200 microns will be utilized, and an infill of 10% will be employed. The car's body should be printed in True Red and all other parts should be printed in True Black. Attach the small axle through the front holes of the car's body, followed by attaching the small wheel to its end.
