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.
This model has be taken an uploaded from;
