The university here has one in the CS department somewhere, although I've yet to actually see it in person. I was told about a week ago they print stuff for free, so long as we designed the blueprint -- provided we get permission from some department honcho. The only real bottleneck about the whole deal is how long some of this stuff takes to create.
A 3D printer is something I've long dreamed of owning, even if it's a basic MakerBot or what have you. I'd never have to buy another part in my life! :)
Maybe you can print a case for your Pi? http://www.thingiverse.com/search?q=raspberry+pi+2+case - With the proper settings you can probably print one in less than 2 hours.
Had plans of buying one last year but I decided to hold off until they got a little higher resolution for cost (budget approx $600). Thats pretty cool that your library has one, how much do they charge per print?
