No, I will not be talking about race track parts, but the cars itself. I have seen very little articles when it comes to the 3D printing of cars. This has been a thing for model railway enthusiats for a long while now.
But imagine the posiblities! Want good looking wheel design? You can make it. Want a chassis with a lip and diffusers? Go for it! Want to make a brand new car? You can make it.
