About this 3D model

I had the same problem that everyone else has had, the wires on the x-axis fatigued and broke inside the insulation. I looked at all of the posted solutions and found each of them wanting. The cable chains seemed too heavy, and some of the other solutions didn't control the motion of the cable or required one to reroute the cables. This solution maintains the original cable routing and controls the entire length of the cable. 4/4/16 I have added a new version with a slightly thicker cable carrier to address a potential slicer issue https://www.youtube.com/watch?v=Pk8g16gRuMc http://youtu.be/cD0QYTWYgY0
