PTFE Cable Holder

This PTFE tube holder is designed to replace the original tube holder (last image in the gallery), that works with pneumatic PTFE tube connectors. I designed it so the print head can be connected directly to my external filament dry box with one concurrent PTFE tube.

This design also reduces friction as the narrow diameter of the pneumatic tube connector is skipped, therefore providing a more steady flow of the filament. I use a 50cm long concurrent PTFE tube with an inner diameter of 2.5mm and an outer diameter of 4mm. You need to also use cable clips to hold the tube in place, as shown in the pictures.
