The Apprentice Starkiller's lightsaber from Star Wars: The Force Unleashed (1)
There is a bit of the blade left on the emitter, as I could not cut it off in Netfabb without slicing off part of the emitter shroud. Model file acquired through Grabcad and modified to .stl file. Someone with Netfabb Pro could edit this to create a more printer-friendly model, eliminating the chunk of blade on the emitter and combining any loose parts. The crystal chamber rods should also be replaced with metal rods for better structural integrity.
EDIT: The parts are very small, so they must be scaled up (around 7 or 8 times their size?) to make them life size props.
