Over/Under Cable Chain
This is the cable chain system that was developed for the PAW 3D printer project at bearcnc.com. There are other pieces specific to the PAW but the main body is made up of the Over and Under individual links.
It's rather simple yet very sturdy and easy to print. The links lock to each other strongly and are difficult to accidentally pull apart. Just snap an over to an under around your wiring and repeat till its long enough no secondary parts per link are needed.
