Bambu Lab X1 Carbon Feeder 8-way

Updated 2026/1/22

• Added a taller version for smoother filament feed (on the second plate)
• A PTFE cable clip complements this feed port (on the third plate)

Corrected the thread direction issue

===============

I explored numerous filament feed extension solutions, but none proved entirely satisfactory

Reasons

1. Primarily, the AMS exerts considerable tension, and without a pneumatic fitting, the PTFE tube is prone to dislodging

2. The AMS lite retraction distance is quite short; adding a multi-way connector to the feed port limits the AMS lite to only three channels

-----------

Therefore, I redesigned the feed port. It currently features eight ports: four for the AMS lite, and three for manual filament feeding

Note:

• Requires seven pneumatic fittings. Refer to the image for the model number
• Instructions for feed port disassembly are available on the official website wiki
• The original feed port incorporates magnets, thus, replacement may affect functionality; the precise function is unknown to me 😄, perhaps filament jamming detection? I have not yet encountered any issues
• If too loose, consider slightly enlarging it
• PETG printing is recommended. The printed part is considerably less robust than the original, and its longevity is uncertain. It has yet to fail, however
• The overall design is somewhat bulky
