After disconnecting the cable bundle and moving the ptfe tube, the cable bundle/ptfe tube would get pinched between the control arm and the frame during a homing sequence causing the motor to grind and skip.
I made this to keep the bundle from getting below the frame and getting pinched.
Uses the existing frame screw to mount. Make sure you get a good bite with the screw or the model will pop off when there's a little pressure applied. A slightly longer screw wouldn't hurt, but I was able to mount it with the stock screw.
