I run a small vacuum forming business. I make a lot of movie props. I did some work for a guy and he made a 3d drawing for me. I uploaded the design to shape ways and the prices were crazy. I think the parts need to be hollow and I would like to make some changes to the design. I also need three of the parts to be half the size. I was planning on resin casting them after I print them. Unless, I can print them at a reasonible price.
