Check your local libraries too. I know that OSU's library has a 3D printer, although you have to have a student account for them to charge. The charges basically just cover material costs. If anyone finds other libraries or resources in oregon, I think we could all benefit from that knowledge. Check out Thingiverse.com for lots of star wars related items. You can download the 3D models to have printed. They are free to download. I've seen Leia's ANH blaster, biker scout blasters, compads and lots of other things on there.
