Filament Pass-Through Fitting for 3D Printer Enclosures

A simple threaded filament guide designed for routing filament through a 3D printer enclosure. The main body passes through the enclosure panel and is secured in place using the included nut. Filament enters through the upper opening, while the threaded lower section accepts a standard PTFE tube fitting, allowing the filament to continue smoothly through a PTFE tube toward the printer. Useful for keeping filament paths organized and reducing friction when the spool or dry box is located outside the enclosure.
