This is a self watering pot insert for the 10cm Ikea Salpeter plant pot.
The insert perfectly fills the pot and the 2 slots on the side can be used to water the plants. The slots also come in handy to lift the insert out of the pot.
The bottom of the pot is tapered, to reduce the amount of soil that remains in contact with the water. Let's see if the peace lilies like it.
Printed a few of them in PLA. Will see how long they last…
