Hello! This is my third design using fusion, it's a lightsaber blade that attaches to CEO51378's Obi-wan Episode 1 Saber.
This blade is comprised of 3 pieces. You will need to print the base which will attach to the handle, middle which will attach to the base end, and the end cap which will round off the blade. I hollowed out the blade to reduce print time and allow you to add led strips if you're going for that style. Each piece connects with threads and the print profile is setup to block supports on the threads, the only supports are inside the blade itself which pop out easily.
I printed the blade in Sunlu glow in the dark blue!
