This is a customizable filter that you can connect to a hose or intake pipe. I created it to allow water changes with a hose while preventing fish or plants from being sucked in. I suppose you could also use this to replace a broken intake filter as well.

The "holes" in the filter section are approximately 3mm x 3mm.

Notes:

I printed this vertically at a slower speed and slightly lower extruder temperature in order to allow for successful bridging while doing the upper conical part.

I suggest using a food grade/food safe filament. This probably means avoiding ABS, and sticking with clear/natural PLA or PET/PETG.
