The cooling tower has a bottom with drain holes as well as root level watering feature. Add water in the slots on the front and back of the rim, and the water will flow down into the central ring and drain out from there. (Some plants, like Venus Flytraps, benefit from ‘root watering’, this planter allows the water to enter the soil at root level, rather than from the top like plants are traditionally watered).
The model pictured also has a place for planting another plant in the large rectangular building, with an open bottom (my wife had requested a planter that would allow one plant to be planted directly in the substrate of the terrarium, and one that would allow a plant to be separated from the substrate below). But I've also included two additional versions: one with a bottom with drain holes, and one with the building solid.
Normal print settings should be fine, no bridges, and all the angles should be printable with average cooling capabilities (ignore the layer lines towards the top of my cooling tower, I have since cleaned off my z screws, woops).
Footprint is 95mm x 155mm.
The author marked this model as their own original creation.
