Perhaps you could try JLCPCB who also offer a 3D printing service. I've been using their PCB service for over a year and it's excellent and extremely cheap. I suspect their 3D printing machines are better than what you use at home.

If Shawn would upload his files, I would be happy to get JLCPCB to print them.
