The file 'Dryer Hose Connector 3D Printer Model' is (stl) file type, size is 32.6KB.
A connector that fits on the end of a 4 inch dryer hose, to reduce the size.
I made this to reduce the size of the dryer hose and give it a rigid end to use with a piece of XPS foam that I use as a gap filler. This goes along with the fume extractor I did https://www.thingiverse.com/thing:6742420. The outer diameter of the smaller end is 72 mm (2 53/64 inch) and the inner diameter is 68 mm (2 43/64 inch).
In case this size does not work for you, the inner diameter of the larger end is 112 mm (4 13/32 inch). The hose will easily push in, but be snug enough to not fall out.
