The Bowden Tube

The path for guiding the filament from the extruder to the hotend is a standard PTFE/Teflon tube at 2mm ID 4mm OD for 1.75 mm filament

I recommend approximately 80 cm of ptfe for this path

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

I recommend approximately 80 cm rod for this path

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

I recommend approximately 71 cm of loom for this path
