DeWalt™ AirLock™ Inlet Hose Adapter 45mm (1 3/4in)

I modified the inlet hose adapter for the Dewalt Airlock system that Allen Derusha designed. This fits my medium sized Ridgid shot vac that has a 45mm (1.75in) OD hose. Like a good upstanding citizen of the internet, I uploaded the CAD file as well.
