I created a new model for Revan's saber since I wanted one that looked like it does in the game.
The model by CaseStudyno8 (https://www.thingiverse.com/thing:1735267) is great, but have four prongs, in game it has three. So I decided to model one from scratch based on screenshots from the game.
There are two versions, one with the full hilt if you have the printing space for it, and one that is split for smaller print area.
Edit: Added an additional version with a hilt that has grooves in it and the spikes separate. You need to print three spikes besides the body obviously. The hilt and spikes have a 0.4 mm gap, so fitting them should be fairly straight forward.
