Honda has started releasing STL's of their concept cars allowing people to print them. There are two different files, one is low res @ about 10Mb while the high res file @ just over 100Mb. The site itself shows the prints being done on a Makerbot so nobody should have a problem printing.
Under the T's & C's it allows anyone to use and distribute the file but not to make an monetary gain from it so its open to anyone to publish.
This are not my own model.
