It turns out a car with square wheels is possible, you just need the right road!
This model is designed to be printed with no supports. The car is printed on either side (sometimes turning print speed down a bit will lead to slightly more successful results)
I printed the road on its side in vase mode to save material and it works great for demonstration purposes.
