Dewalt DWE6421/23 to Rigid NXT Shop Vac Adapter

Rigid NXT Shop Vacs already have a rotating coupler on the end with a locking attachment. I designed this to attach the shop vac to Dewalt DWE6421/23 orbital sanders. This adapter has a feature that helps still utilize the locking attachment and ensure it stays on.

I recommend eight perimeters on the "toothed" section to ensure it is sufficiently rigid. You can add a modifier in slicer to add more perimeters in that section of the print. It should be printed with the toothed side down, no supports required, and relatively quick print.
