Lose the coupler to your Galaxy's Edge Shadow Maul lightsaber? I got you covered with this model! I tried to get the measurements as accurately as I could, but after a few iterations decided to increase the tolerance on the side that connects to the SM lightsaber hilt so that the screw doesn't break the plastic once tightened. This coupler will only work with the Shadow Maul + Legacy Maul hilts, and will not work with 2 Legacy Maul hilts due to the one-sided threaded design.

I've printed and tested this coupler with PLA and it works no problem, but stronger material may be better for long-term reliability. I unfortunately have not tested with other materials at this time.

I'm open to suggestions/feedback! If you do end up using this coupler and sharing it around, I just ask that you give credit, as this is my first 3D model to upload for the community! :) Good luck and may the force be with you!
