I made a custom 3D-printed ant nest, inspired by ANT AND's enclosure. The listed photos show example ant nests. Basically, it will be shipped without plaster or concrete poured in. If you would like plaster or concrete poured in, please let me know in the comments. Nests with plaster poured in are designed to be watered, while nests without anything poured in, or with concrete poured in, are used as dry nests in my own ant keeping. Concrete nests are used as a refuge for eggs, larvae, pupae, and cocoons, etc., when the plaster nest is overwatered and moisture seeps to the surface. Multiple purchases are possible; if you wish to purchase multiple nests, please indicate the desired quantity in the comments. In addition to black, there are red, green, blue, white, and translucent colors available. If you would like a color other than black, please specify your desired color in the comments. Since these are handmade ant nests, I will remove any imperfections as much as possible, but there may be some remaining stringing or burrs. Thank you for your understanding.
