low liquid level siphon

I designed this to print without supports. If you add supports it will close the holes.

I use this to empty as much water as possible out o my spa (hot tub). (Without opening pipes) I place it at the lowest level and place a heavy object on the large ear.

The profile is kept short to allow as much water to be siphoned out without sucking air into the hose, while the sides are kept open to allow as much water flow as possible.

I used natural plastic (Makerbot) because it is the hardest that I currently have, but prob the worst option for photos.
