I've just received my printed UVEX parts from a commercial 3D printing and fabrication house (using laser sintering in nylon PA12, which has much better properties than more common nylon 6). It's not a cheap method, but the parts are very, very rigid, with a nice smooth finish. I have difficulty believing that metal parts with realistic dimensions would be very much more rigid. I won't have much time this weekend, so it probably won't be until the following week, but the next task will be to test IR opacity, and then to assemble the optics.
It would be very useful to have a schedule of the specific metal parts (unless I've missed it somewhere) - I can kind of figure them out from the pictures and instructions, but I'm guessing at some of the lengths needed for the hex bolts etc.
