The file 'Portable Air Conditioner Accordion Duct Collar For 5″ Ducts 3D Printer Model' is (stl) file type, size is 81.6KB.
This is a collar to mount flexible, 5" accordion duct to a drop ceiling or plywood, etc. It screws in to the duct.
The outside diameter is 169mm to allow it to be printable on most printers.
I have added a second model that includes screw hole studs for mounting the collar to plywood or like material.
