These are some Modern-esk hexagonal plant pots. They have all the same footprint and the same built-in water tray. There are smallish holes at the bottom of the inside to allow the tray to serve as a reservoir.

The mid-sized one was designed to fit a "standard" small plastic potting pot (100mm diameter at top, 70mm diameter at bottom, 7mm tall). The idea being we can bring a nice indoor plant home and put it directly in this hexagonal pot. When the plant outgrows the pot it came in, we can move it into the hexagonal one.

The taller one is used when the plant even outgrows the mid-sized pot and the shortest pot is used for cactii or other small plants.

The pots shown in the photo were printed in the Ziro Marble filament. It's gorgeous and prints really nicely on the Prusa i3 MK3/S. I printed every single one of these pots (5 in total for me, 1.5 kgs) in this filament without a single printing error.
