These Hanging Planters are quite simple to build and work extremely well.

Apart from the 3D prints, you'll only need some rope with a diameter of roughly 2mm

If you print them in white PLA you can sand them to make them more smooth.

The water bucket will slowly leak water so you will need to put silicone on the inside walls or something like a plastic bag. Preferably just put a normal plant below the whole setup that catches the excess water.
