I present to you the foundational formicarium KingFoundationV2:

It has the following characteristics:

The tube should to be of : 15,70mm +- tolerance your Print3D

Modular moisture system, when the water in the tube runs out, it can be replaced by another filled tube without disturbing the ants. Feeding system through a syringe through a small hole. Expansion system when the colony is already founded, you will only need to rotate the queen's chamber until the large holes coincide, there an expansive module or foraging chamber will be connected.

I hope you like it.
