Shrimp guard for Fluval Skimmer

prusaprinters

I made this to fit in the throat of a Fluval surface skimmer. It keeps fish, shrimp, and snails from getting sucked into your filter. Print with no top/bottom, and adjust the infill shape and percentage to get the hole size you want. Keep in mind that tiny holes won't let much water get by. If you have trouble getting it to friction fit, try scaling it a few percent larger or smaller.
