Corben,

Well done! I teach middle school science and have 3 3D printers. I would LOVE to get this started in my curriculum. I am writing a grant for the CO2 car materials. If you have any advice on what to buy and what to leave out, etc, I would be grateful. I assume I need a launch system, axles, wheels, and cartridges. We can design and print the bodies. Any advice? Thanks again!!
