Protein skimmer for sea water aquarium

Protein skimmer to a sea water aquarium.

I added video from the collection cup.

Printed in PLA, but there are some issues.
Because it´s in an aquarium, I didn't use anyhing such as XTC-3D to make this
watertight, because I'm afraid that XTC-3D would harm the inhabitants in some way.
So there will be some water which will penetrate parts, and there will be some air bubbles
coming through underwater parts in some period of time.
Also remember that PLA is biodegradabl
