Rubber Band Car

thingiverse

This is the first rubber band car I created. It uses 3 mm wire as the driving axle, and bicycle tube rubber for traction. With 2 rubber bands connected in series, this car could easily run for 5 meters and more. The screw holes for the front wheel axles are to be tapped for m3 screw. The other holes are plain. For the rear wheel axle I used 3 mm iron wire (here usually known as clothes hangline wire, bought 1 kg at local hardware store), notched at the middle, glued and tied with another small piece of wire with matching notch. I Included the thicker rear wheel in case more strength is needed. The thinner wheel was easily broken with rough playing with kids.
