Top Filament and PTFE Tube Guide

Top Filament and PFTE Tube Guide

After I bought a filament dryer, I also had to think about a new way to feed the filament. To do this, I designed this cantilever to guide the filament over the X-axis of my Anycubic Kobra 2 Plus.
The model is available for PC4-M6 and PC4-10 pneumatic connectors.

Update 2025-08-10:
I have added another model to which the runout sensor can be attached, allowing the PTFE hose to be connected directly to the hot end. This model need 2 PC4-M6 pneumatic connetors.

NOTE: Due to the long way, I use a 4mm x 2.5mm PTFE tube. My matt PLA caused problems at this length and was very difficult to pass through the 4mm x 2mm PTFE tube, which had a negative effect on the print.
