AeroGarden Water Level Float

I'm building a hydroponic growing system somewhat similar to an AeroGarden Farm. I needed an inexpensive way to check the water level. A 3D printed structure roughly the size of an AeroGarden pod and a dirt cheap 3ml dropper from Amazon does exactly what I needed.

There is a notch in the side to allow the power for a circulation pump and an air stone supply hose to use the same opening.

This should also work for an AeroGarden with a failed water sensor.

The dropper is here: https://www.amazon.com/gp/product/B09VBRPR7J
