My bad, I thought you had the table top model.
Below are some photos of my Kreg router table setup today, some six years later. I add some drawers and some dust collection. The one photos with the black tube, is inside the dust collection box. The white tube, that is cut into the black tube, provides suction pickup for the fence. The collection extends down below the blue rails.
This shows the main 4" vacuum line and the smaller suction line going up to the fence
This is a picture inside the dust collection box. the black tube is the 4" suction line from the cyclone. The white tube, that is cut into the black tube is the suction pick up for the fence
