Jebao Sw2 sw4 Anemone guard sw-2 sw-4

Isn't beautifull but it does work. Is made to fit jebao sw-2 and sw-4 pump (they have same size). and maybe others.

Is made to let 0.7cm of gab between pump and guard wall in order that even if anemone stick tentacles in the holes, is it harder to arrive to the turbine. Hopefully it will save some anemone. Print without support unless you want to poke one by one all the holes.
