My print washer is a plastic container form the local hardware store with a Plexiglas false wall at the drain end to force drainage from the bottom. The separators are Plexiglas held in place with PVC trim. Water is injected in each section from a plastic pipe clamped to a water hose. The “jets” are 2mm holes drilled at appropriate intervals.http://www.doak.no/index_files/3-DarkRm.htm
