This is a VERY simple thing to make all you need is two lightsabers and a normal stick piece of lego (like the blade of the lightsaber). ALl i did was cut a small piece off of the stick piece of lego. And then placed it in the one end of one of the lightsaber handles, and then put the other handle on the other end of the piece.
I made a moc just like this in April. I wouldn't mind, but you didn't even say like, I got this idea from some other moc page. NOT COOL. NOT COOL. (if you don't know where the idea came from, just say i got it from somewhere else, and i don't know who made it.
