CO² racer

This is a small flat CO² racer. I chose this design for a good amount of down force and minimal air resistance. Easy to print but would need some glue for the wheel carriages and a 3mm kopper rod (you can use something different) for the axels. It was also meant to put O-rings around the tires for grip. Also put the ipt file for the racer so you can add some fun stuff like a number or name (like on the pictures), It is meant for a 16g cartridge but you can change it to desired diameter or length
