A remix of the cable chain the majority of us use. This is adapted for use on the HICTOP Prusa i3, but might work with similar configurations and clearances on i3s.
This system is designed to mount to the carriage and to the X axis stepper motor. The chain goes behind the Z axis parts which makes for a nice look.

ABS or PLA can be used. I would advise using ABS for the part that mounts to the motor because it gets really hot. I used ABS for the chain and really like its sturdiness.
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 these holes should be approximately 4mm diameter.
