I was in touch with several 3D printer people some years ago when I had wanted to reproduce some old H.G. Palmer labels and wheel caps. The prices varied enormously from one seller to the other. One seller on the coast wanted $350 for one wheel cap!!! Another person wanted a more reasonable $11. A local university offered to make them for free. I was told that there are many different types of printers and many different types of plastics. As Gadge suggested above, only accept ABS or nylon or similar. Anything else could result in failure in a very short time.
