Aquarium Filter Strainer 12mm

I need a filter strainer that can suck from bottom of the aquarium with larger holes. This strainer fits 12mm eheim inlet hose and replaces the small strainer. Holes are big enough to suck plant residues but not allow fish or snails to get inside. Inlet  holes are in the bottom of the strainer, so the strainer sucks from bottom. If placed on the substrate it will not suck the substrate but collects all the dirts in the aquarium.

Printing with low layer height is recommended to overcome algae growth but not necessary. Pla is ok. Tolerances are somewhat tight so calibrated material and printer is needed.

Print without supports.

No glueing is needed after printing.
