This is Darth Vader's lightsaber from Star Wars Episode 3 - Revenge of the Sith.
I did the 3D model with the Master Replicas prop as reference, so the model you'll get is as accurate as the one used in the movie :D
In this, you will have all the files to print this saber, and a 3D model of it completely assembled.
The files are for a personal use only
Happy Printing :D
