A strainer to keep all the sludge out of the pipes
Included are the new PrusaSlicer 3mf files for the pieces.
The main part contains a bridge cap for the overhangs to avoid rafts. One of the images shows it being cut away with an exacto knife.
The strainer insert uses a trick in the slicer. Adjust your slicer for this piece to have zero top and bottom layers. Set the infill to 40% or better. Choose an infill patter that's attractive and will let water flow through easily. On my slicer I chose "star" pattern. When it prints without a top or bottom you're left with a nice looking screen.

I had a slight amount of elephant foot and the screen did not insert. I used the exacto knife around the inside edge to cut a small chamfer. The screen then fit nicely
