Anybody look into these guys yet? They have a really great interface, and print out miniatures for D&D and stuff. With some eye-squinting, you can even make a miniature Mechwarrior or something.
For reference, here's a D&D Character I made using the site. Yes, it's a furry, and it's a dual wielding ranger. But this is just one of a fair amount of stuff you can make. They also 3D print the minis in four different types, and you can even make statues in plastic of your favorites. If you want to make strictly Btech RPG stuff, some of the sci-fi stuff looks Mechwarrior-esque. A bit cutesy looking in a way, but not awful.
