Hanging Fish Feeder

I don’t really like to turn the return pump off when I feed the fish. And I definitely don’t want to spend 20 bucks for a piece of plastics. I hope my design is simple enough for you to print, no tool required, you can just print and snap them together.
I have a Nuvo Fusion 40 AIO tank.

Please check out the video before downloading/printing the part, so you know how they go together.
