Stackable "Tuna Can" style space habitat

a stackable “tuna‑can” style modular space habitat, inspired by speculative engineering concepts and NASA‑style mission architecture. The goal was to create a 3D‑printable model that is both imaginative and structurally logical, while demonstrating how modularity can support long‑duration off‑world living. Current material is ABS plastic. Window features are meant to be clear. The habitat is built around a cylindrical, vertically stackable form, allowing multiple units to be combined into larger colonies or rearranged depending on mission needs. Each module contains four functional stages, representing the essential systems of a self‑contained space habitat: 1. Upper Command Stage This section houses navigation, communication, and mission‑control systems. It is designed as the “brain” of the habitat, coordinating operations between the other stages. 2. Living Section Stage This mid‑level module represents crew quarters, life‑support systems, and shared living spaces. Its cylindrical ge
