Self watering wall mount flower pot system. These are stackable and easy to water though the watering holes. Use a small spouted pouring kettle or print a small funnel to water without spilling. To have the self watering effect you will need to make a wick from some old cloth or similar that goes from the water reservoir and up to the inner pot.

Seam position is very important for watertightness. I have printed it watertight on a Voron, but take care to check if your print is watertight before you mount it to a wall.

Enjoy :)
