The file 'Fan Duct Adapter For Ceiling Collar (4 Inch) 3D Printer Model' is (stl) file type, size is 60.3KB.
I made this to connect the fan duct from the back of my Anycubic Photon to the bathroom ceiling vent. You will need a ceiling collar, the metal springs from inside a vent cover, and two zip ties. After printing, I lined the adapter up on the ceiling collar and drilled two holes for the zip ties to pass through.
