One material for the HILT using 4096 x 4096 textures. The lightsaber blade is made up of an inner and outer model with an emissive applied the blade is not part of the HILT unwrap.

This is not designed for 3d printing, as in it’s not watertight. And the details are painted on. BUT a person exerienced with 3d printing should be able to set it up to do so.
