Sculpfun S9 Cable Strain Relief

This is a remix of the stepper motor strain relief by AndrewBCN. I updated the size of the zip ties holes and location within the 'cup' to take the strain off the thin area where it connects to the arm. On the x axis one, i included a grove specifically for the Sculpfun S9 where the motor mounts. On the y axis mount, i moved the arm more towards the center of the mount to allow the harness to be more inline with the x axis.
