hospital complex 3d model

Create a detailed architectural 3D model of a hospital complex based on the provided reference image. The model should be designed for 3D printing on a Bambu Lab X1C (maximum print size 25 cm), but the final scale must reach 40–45 cm in total. • The building must be split into 2 printable parts along a clean flat plane, ideally dividing the complex into two main blocks connected by the bridge. The split should ensure easy assembly after printing. • The bridge connecting the two buildings must be hollow inside, keeping walls and roof only, to achieve realism while saving material. • Maintain proportions, architectural details, windows, roof tanks, and HVAC units. • The two parts should have flat, precise joining surfaces. Optionally add cylindrical alignment pins and matching holes for easier assembly. • The model must be watertight, manifold, and optimized for 3D printing (no non-manifold edges). • Export in STL or 3MF format, aligned correctly for slicing
