Vacuum Reducer for Cyclone Dust Collector

I needed something to attach my small vacuum hose to my irregular size dust collection cyclone. All the universal ones i've purchased just don't fit. I am attaching the .stl file so you can edit it to your needs. If I were to do it again, I'd make the walls a little thicker. Otherwise, this will be sufficient for my needs.
