I designed this small modular vertical planter after seeing something similar in a local greenhouse and wanting to create my own version for 3D printing.

To hang it, I used waxed thread and tied simple knots every 15 cm to keep each planter spaced out (though you can adjust that however you like depending on your setup).

It prints easily with no supports needed. If you’re planning to hang it somewhere with a lot of sun, I recommend using PETG or ABS so it holds up better in the heat.
