You can find out several paper folding artifacts on Gadgetsin, but I think the following subway tickets origami artifacts themed by Star Wars should be the best paper folding artifacts at present.

If you also want to create own great paper Star Wars spaceships, please follow the steps posted by Hubert de Lartigue.
