Venturi air-water pump
thingiverse
There a two venturi air intakes you can print easily. You should connect the small connector to the air pump and the large connector to a pipe that will carry the water to the location you want (e.g. in your aquaponics growbed). The lift is however limited, depending on your air pump it can be 10-20cm. There are two versions proposed: - the first is a simple remix of https://www.thingiverse.com/thing:2499477 . The modification is to have a vertical connector for the water. - the second is an original design. Instead of injecting large bubble it uses many small holes to generate many small bubbles with should be more efficient to lift water. It is inspired by this video https://www.youtube.com/watch?v=trqCIKXtYig You can see it in action here: https://www.youtube.com/watch?v=M_YMewBTQvI
