I wanted to create a cable chain system for the M2 that does not require rewiring or modifications to the frame. This system has 2 piece links that allow the chain to be applied over the existing cable shielding. The chain ends mount with existing holes. The head end replaces the existing cap that holds down the cables and is held in place by 3 small zip ties. The frame end will need to be held in place by a 3/4 inch bolt and nut and utilizes an existing hole in the frame. It took 22 links to fully cover my existing wiring but that may change from printer to printer.
