A 3D print can only be as good as the 3D file and the plain fact is they're made of flat'ish pixels so will never be smooth like a well polished injection molded version.

I'm one of those willing to overlook the imperfections to have a car that otherwise isn't available. It's all part of the scratch building side of our hobby.  

Maybe I should consider trying carving as an option, in a lot of ways would be much easier and quicker than 3D file creation.
