This is the lightsaber of Yoda from Star Wars Episode 3 - Revenge of the Sith.
In this, you will have all the files to print this saber, and a 3D model of it completely assembled
I wanted to do a really accurate model, and the Ring is a bit fragile, I suggest you print several Rings and not glue it on the saber, you'll be able to change it if it breaks ;)
The files are for a personal use only
Happy Printing :)
