DeWalt AirLock twist-lock dust collector fitting

I remixed the fitting to work with my Dewalt DXV10S Shopvacc that has a 2 ½ inch hose (connector is 45mm in diameter).

I recommand PETG to get a bit of flex, but PLA can also work, it'll just be a bit stiffer

Assembly

The outer ring should slide freely onto the inner ring, and when all the way in the top layers should be flush. If they aren't, you have the outer ring on upside-down. With those two pieces together, you then can press-fit the hose adapter to the bottom of the inner ring. Position the hose adapter against the inner ring and then use a vice, bar clamp, arbor press, etc to squeeze the two together. The fit should be TIGHT and once pressed together I have been unable to remove the parts without destroying the plastic itself.
