A remix of the beloved cable chain most of us use. This is adapted for use on the HICTOP Prusa i3, but may work on other i3s with similar configurations and clearances.
This system is designed to mount to the X axis stepper motor and to the carriage. The chain goes behind the Z axis components making for a nice clean look.
ABS or PLA can be used. I would recommend using ABS for the part that mounts to the motor since it gets really hot. I used ABS for the whole chain and really like the sturdiness of it.
The STL file for the carriage mount does not have holes for the carriage due to variations from model to model. Post print, use a small drill bit to make holes for mounting. The size of the holes should be around 4mm diameter.
