I recently upgraded to the AMS-hub for my Bambu Lab X1C and didn't see any exhaust vent mods that fit it so I decided to remix one and make a few changes.
This exhaust vent is designed to fit a 4"/100mm ID ducting hose. There is a slight taper that should help with putting the hose on.
3 holes surrounding the exhaust need to be tapped. They tap easily for m3 screws and the model is designed to use it. There is a fourth hole on the left side that lays on top of an existing screw but you don't need to use it and I left it there as an indicator for alignment.
BOM:
3x M3 x 6 hex socket head screws.
