A printed water scrubber that hangs from a plain 5-gallon bucket lid, on the exhaust side of the vacuum in the sealed dust-train cabinet. Two lower stages screw onto the same socket. The honeycomb fires the air through holes under the water, and dust that gets wet sinks. The venturi sprays pool water into a fast throat and throws it at the pail wall, which catches much finer dust for a little more suction. A demister turns the air back on itself to drop the mist. Every part here is exported from the CAD model. Drag to turn it, pinch or scroll to zoom; the flow shows where each kind of dust ends up.
