Cable Chain - open sided

This one cable chain is remake of chain from https://www.thingiverse.com/thing:60002 .
I made some tweeks ;-)
1) I made two pieces so there's pair now
2) Both pieces I opened one side, on the 1st one one side, on the
2nd one the other side so they could be easily added to already installed and connected cables/wires and will do their job ;-)
3) I made it more rigid and sturdy so the installation is a bit more difficult but it more likely won't fall apart while moving during print
