Bambu Lab P1S Vent Attachment

A custom 4" duct attachment for the P1S. Intended to be screwed in using the vertical holes rather than the horizontal ones the manufacturer recommends. My motivation was to use less material, and I hadn't read the manufacturer's guidelines about exhaust duct adapters yet. It is snugly attached and has not yet exploded. It fits a bit too snugly with an aluminum semi-rigid duct, sizing it down a tad is recommended for those.

The included .3mf file is configured so that the infill density is 100% in the screw region. I recommend pre-drilling here. I used machine screws I happened to have that happened to fit. No screws that came with the P1S did the trick.
