My son designed his entire car himself in TinkerCAD and is 3d printing it. Which is great because I have a 3d printer but I don't have any woodworking tools except for a crappy hack saw that I have actually used on a pinewood derby car before and it was terrible.
He's printing the body in woodfill PLA which is about 30% wood fill so it can be sanded and stained. If it turns out I'll try and post a pic.
