Dewalt Vacuum Hose to 2.5 inch hose port adapter

I purchased a Dewalt Wet/Dry Vacuum (DXV10S) and was disappointed to find that its hose did not fit to any of my Dewalt hand or stationary power tools including my Dewalt Table Saw and my RIKON Band Saw which both use 2.5 inch dust ports. This adapter allows for a connection to be made between the vacuum and tools that use a 2.5 inch port.

I found that there was a slight variation in the size of dust ports between those two tools which is why two models are provided. I also provided the SCAD file I used to generate this adapter so that other sizes may be generated. 

For the Dewalt Table Saw (DWE7485), I found that the port tapers slightly and that the 58mm adapter works best. Because of the taper it seats well and makes a good seal on its own.

For the RIKON Band Saw (10-305), I found that the port wasn't tapered and so the smaller 57.3mm size worked better in conduction with gaffers tape to create a more of a friction fit. Because the port is not tapered, the port doesn't have much hold on its own.

I expect that these adapters would work well going between any Dewalt Shopvac style vacuum and tool with a 2.5 inch dust port. Dewalt seems to use the same size hoses with the same ends across their product line. If you try this with other tools, please comment so others can know what you found.
