The file 'CPAP Hose Coupler 3D Printer Model' is (stl) file type, size is 10.7KB.
I needed a way to extend my CPAP hose and had an 8 inch extension I wanted to use but had no coupler. I figured out in Tinkercad how to create a very slight cone. This tapers from 22mm to 22.5mm so it slides easily onto the hose.
