The Anycubic Kobra 3 Max Combo quick-connect fitting holds the PTFE tube at the print head’s filament inlet and along the Filament Hub/ACE Pro feed lines. Its spring-loaded mechanism securely grips PTFE tubes with a 4 mm outer diameter, while the release collar allows them to be disconnected.
The internal funnel guides 1.75 mm filament from the outer tube to the extruder gears without snagging. The fitting attaches directly to the print head’s top cover or the filament hub housing as a replacement part.
