This is my rendition of a formula one car as a pinewood derby car but 3d printed. I would recommend for the best results to print out of carbon fiber and then use some tungsten putty and put it behind the car and under the wing so all the weight it in the back.

I put two versions of rims one that is hollowed out to lessen weight but it has broken off for me a few times so if you don't want to risk it breaking then you can use the solid rims attached.
