An interesting concept: upload a 3-D model of something you would like made. If it's viable,these guys will fabricate it with a 3-D printer for you. A couple of hobbyists have already set up shop and are selling their creations from Warhammer 40K, Star Trek, and Transformers. Needless to say, there is some really cool stuff on the site for sale, especially in the Miniatures section.
