ok so the bad picture above shows 2 cylinders that rotate independently of each other. I want to run a cord through the middle(red line) but imagine that each end has a connector. what I want is the wire in the middle not to twist so that both ends can turn continuously. besides making one myself using skateboard bearings and other fun things is there a connector that is out there premade for this?
I am thinking 8 wires for my project but maybe more if that helps
