The adapters that came with the Sweepy on my Shapeoko4 were not the right fit for my regular ShopVac.
I designed the adapter to fit in the Sweepy with the larger round adapter and then designed the hose holder that fits on the Z-axis carriage in the spare M5 holes. You will need a couple of bolts to secure the holder to the carriage.
