An adapter between a DeWalt orbital sander and a shop-vac hose. Specifically designed to work with a DWE6421.
There are two versions. One for a Shop-Vac hose that is ~1 1/8" OD, and one for a DeWalt hose that is ~1 7/8" diameter.
F3D files for both included so you can customize it for your hose if needed.
