Learning how to print and edit
Working in the space industry would be my dream occupation. Gotta start somewhere, so I printed a model of Curiosity, NASA's latest Mars Rover 
5/9/13 Found Mars Curiosity Rover by ThePlanetMike on Thingiverse 
cam and arm/APXS&MAHLI came out great; mast stumbled near opening at top. body and wheels impressive, but very stringy. Spent much of weekend filing off strings and filing down all blue connectors to fit holes.
5/16 Reprinted mast/cam on Ultimaker two tries: needed to raise temperature on mast toward top so it would continue adhering to base Impressive difference in resolution!
and parts photo find out how to add in the downloaded Thingiverse files; make sure I attribute correctly
