ShopVac coupler for 2.5 inch hose

thingiverse

This is a coupler for the ShopVac 2.5 inch hose, created using OpenSCAD. The initial size was based on measurements of a commercially purchased coupler, but I had to tweak it for printing purposes through some trial and error to get the best sizes and taper. I've printed this coupler and used it with multiple hoses, so far they are working well. Recently made, so the "test of time" has yet to come.
