This print allows the use of a Bowden tube direct to the extruder when printing hygroscopic filaments.
The top is threaded to accept a PC4 M10 fitting (which is actually a 1/8 BSP thread). This fitting has a larger hole inside, so it doesn't interfere with the insertion and removal of filaments that don't need the Bowden tube (like PLA).
I'd suggest printing it with the threaded section uppermost, and supports turned on (including for bridging). You could print it the way it appears on the bed, but you will still need supports.
Hope it helps!
