This is a filter that sits at the end of a DWC raft and filters water that leaves the raft. It prevents stray roots and debris from going into you sump tank. I was using the round drain filters but they are small and would clog. This has a larger surface area and works for a long time without cleaning. The filter is just regular window screen that is attached using regular spline. The filter and the clip is attached using 4x #4x3/4 screws. Be sure and print using food safe plastic such as PETG or HIPS. The clip is designed to fit over 3/4" plywood.

Attach regular window screen to the raft return filter using window screen spline and a roller (just like you would for a regular screen). Don't use aluminum screening if it is an aquaponic system since aluminum is toxic to fish. Attach the filter and the clip using 4x #4x.75 self threading screws (or M3 screws).
