The outlet consists of two parts that easily screw together and prevent the filament from rubbing against the cardboard box. The inner hole is sized to hold on to a 4mm PTFE tube.
Nobufil has integrated spool holders into their filament boxes, which is a really smart idea. You simply download the provided spool holder files (https://www.nobufil.com/box), print them (even the bearings are printable, though real bearing rum smoother), and you can keep the filament spools inside the cardboard box while printing. I really like the idea and it has worked well for me, but the filament is guided throu a hole in the cardboard box and rubbs against it, which creates some noise.
The intention of this outlet was to reduce that noise and to use the boxes with a filament buffer. I am running the PTFE tubes straight from the boxes to the buffer and into ERCF.
The threads work with 0.2mm layers, but I would recommend printing with finer layers (e.g. 0.15 or even 0.12mm).
