Printrbot Simple Metal Y-axis Cable Holder

A modification of "Cable Chain" by ModelStation. My changes include eliminating one wall of the chain pieces so you can slide in the cables headed to your extruder stepper and hot end without detaching any wires. This set of wires always seem to droop into the build plate on the Printrbot Simples, this worked as a solution. I also added a chain end and a stepper motor mount. You'll need some 35mm M3 screws (a little bit longer than the stock stepper screws to allow for the space the mount takes
