A parabolic dish designed for stainless prints. I'm allowing it in other materials, but other materials will not be able to handle the heat. For other materials, I would suggest trimming off the cross beams and using it only as a mold to get a parabolic shape. Now for stainless, the cross beams do have a purpose. the beam that comes down in the center ends 1/32 of an inch above the focal point. This is for when I get it to test it, I can glue a piece of paper or a match head here and hopefully ignite it with the sun. Stainless will have to be polished, and I do not know the full reflective properties of stainless prints.
