I know that Jay Leno 3D prints parts for cars that he's restoring because trying to find parts for old cars is like trying to find needle in haystack especially if the old car is not 1955-1957 Chevy, Camaro, Mustang, Chevelle, etc. What if he's restoring a car so that it looks better than a brand-new car that came from the factory and he expects to win an award?
