That's just it, there is no tooling in 3D printing, I am supplying the .STL CAD file of printing instructions.

The expensive part is the material, there are only a couple of Polyethylene plastic (HDPE, MDPE) that get a B grade for gas and
STRATASYS says PPSF / PPSU (Polyphenylsulfone) is the gasoline-resistant 3D-printing medium you need: (scroll down to the last material)

That means a special large 3D printer to handle it and apparently it's not cheap.

I do have the option to have a mold made from the .STL and then have them injection molded, but again I'd need to make to make a couple hundred just to break even.
