Hello OpenSCAD forum, I'd like to introduce myself and thank  the developers of OpenSCAD for their efforts building a wonderful software package. My question is are their any plastic injection molding companies that will work with native SCAD files? I've got a family of parts designed in SCAD I'd like to build in bulk. The first injection molding  manufacturer I contacted regarding building these parts only accepts designs done in surface model format (i.e. STEP and a bunch of others). I briefly toyed around with conversion of my SCAD parts using FreeCAD but the results were not good.  I'm asking the question here as what I've learned about this subject suggest that it's non-trivial going from SCAD to a surface format and these surface formats are necessary for the  linear/circular G-code used to make molds in the injection molded plastic's industry. I'd like to know if someone on the list has had success building a complicated SCAD part via  injection molding. If so who did you use?  Thanks in advance for your replies and feel free to contact me privately if you have a name.  Best Regards Scott
