This is a simple coupler for 3DPRINTINGWORLD's Collapsing Sith lightsaber. It is simply the cap part with a thread on the top as well. Once put together you can have a double-bladed saber! This also works with the custom saber found on my page.

Printing Settings: ᠎ Supports are not needed as the overhangs aren't bad. I didn't use supports and it is smooth (you can see in the image.) I didn't use adhesion, but a raft would be best if you chose to do so.
