The Rod

To hold up the bowden tube and cabling  while containing a smooth arc from the frame to the X-Carrier I use a 4 mm fiberglass rod which I cut from a cleaning tool I got in a DIY store

The Loom

To hide and keep the cabling in place I use this cable organizer and it works as a cable chain in conjunction with the fiberglass rod
