Toy Formula

My son had been asking me to print him a F1 car, but I didn't find anything that would be quick and easy to print, so I made this thing...
It's a F1 car with toy-like proportions, and it can be printed quite small quickly, or scaled up for size.

Thing consists of 2 models: Chassis (you need one) and wheels (you need four). Print separately, then click the wheels in place and start racing.
