2.5" hose adapter for shopvac and dust cyclone

Designed to couple a 2.5" (shopvac style) vacuum hose to my dust cyclone. Small end fits really snugly in the hose itself, and the big end fits great in both the shopvac and the cyclone ports.

STL originally uploaded has been replaced by a better version with a chamfer (this time rotating an edge profile in onshape instead of only extruding cylinders). This version prints better than the original, which had a lot of stringy bits near the size transition region.
