Check Out This Incredibly Detailed Fan-Made Lightsaber!
I don't think I've seen a lightsaber this detailed, not even in the Star Wars films. Martin Beyer of Graflex Saber took his custom creation above and beyond on the outside and inside! This thing has a soundboard, the ability to change colors, and an actual lightsaber crystal within that you can remove and reconstruct like you are a real Jedi!
Seriously, the level of detail on this is astounding and must have taken an extreme number of hours to build. Unfortunately, Beyer is not selling these, but you can check out this and his other 3D work on his site!
