What a smart-ass remark, full of science and real life! For someone who a few hours ago didn't even know that left handed thread coupling nuts could be seen in the world you're surely impressive. In its own way.

Show us your handiwork, please.

It is easy to sit at a computer monitor with Google and an engineering book, but sifting out real application is something one has to do. Do! You get it? I'm retired but a major effort of my employer was fabricating and testing composite materials, among other materials. There are a lot of surprises that occur regardless of the maths, and therein are the profitable outcomes.

I believe the way it works is that one side is right-handed, the other is left-handed, so turning the nut in one direction tightens (or loosens) both sides at once.

This reads like two MEs sniping at each other over the cube sides. As the assembler waiting for them, if the parts weren't face to face to tighten against each other I would spin on a jam nut to keep things stable. Coupling nuts are often used to join two pieces of all thread, it's safer to add jam nuts than rely on contact between the rods. On my camera gear at least I have no threaded parts that will not go face to face; nothing extra is needed.
