Aquarium Pump Filter Cover

I designed this to prevent small fish from being sucked into the filter, after unfortunately losing two before coming up with this solution.

There's a sponge inside to help protect the fish from injury, and it seems to be doing the job well so far.

I printed this using Tree supports. I did have a few failed prints where some sections didn’t print properly due to lack of support—though that might have been caused by my slicer settings. That said, I also got two really solid prints.

Be sure to use PETG filament, as it's safer and more suitable for aquarium use.
