Hercules Dust Extractor hose adapters

Harbor Freight recently introduced the Hercules 12 gallon HEPA dust extractor which caused a sensation on YouTube because of its price and performance. I bought one. It comes with a spiral corrugated hose and 2 adapters to fit various tools. I have a pivoting dust boom which has 2-½" dust hose fittings on each end to reach my table saw and CNC router. I wanted to connect the Hercules dust extractor to the boom, so I modeled a 2-½" male adapter that threads on the dust extractor hose and plugs into my boom (see photo). Since I already had the threaded end modeled, I also made a female adapter.
