This is a modular ant nest system based on 100×100 mm units. Designed for 3D printing, preferably in PETG, due to the integrated central humidifier. PETG offers better resistance to moisture and deformation over time.

The module includes standard 10 mm tube ports and can be expanded by creating other compatible units using the same format. The geometry is simple and requires no supports.
Print recommendations:

Material: PETG or ABSLayer height: 0.2 mmPerimeters: 3–4Infill: 30–50%Supports: None

Screw holes are sized for M3 self-tapping (2.5 mm). Compatible with medium-sized ant species like Camponotus, Lasius, or Messor.
