Camlock for Dewalt Orbital Sander

This allows a Dewalt orbital sander (DWE6421/DWE6423) to connect to Peter H's camlock fitting. It should also be compatible with other dewalt tools that are designed to connect to their dust extractors.

I designed the connector to be attached by filament pushed in to a few holes around the perimeter for retention, but my test print fit so tightly I can't pull it off. I could remove it by breaking the print, then print it again slightly larger to test the retention pins… but that seems wasteful.

I've included the model files for easy modification, in case you want to make it slightly larger.
