I needed a way to collect the sawdust shooting out of my Ryobi Table Saw so I placed a board underneath it and cut a hole in the center. I 3D printed a funnel vacuum attachment to connect my shopvac I bought at Harbor Freight.
The design also have a coupling to fit the hose to the funnel. Changing just the coupling allows this design to work with any size vacuum hose.
Full details of the project are in my latest Filament Friday video on YouTube.
