hospital complex 3d model

Create a detailed architectural 3D model of a hospital complex based on the provided reference image. The model should be prepared for 3D printing on a Bambu Lab X1C. • The maximum print size of the printer is 25 cm, but the final model must measure between 40–45 cm, so the building should be split into 2 parts with a clean, flat division plane that allows easy assembly after printing. • The bridge connecting the two main buildings must be hollow inside to achieve a more realistic look once printed. Ensure the bridge is structurally sound but open in the middle. • Preserve proportions, structural details, and architectural features (windows, roof details, water tank, air conditioning units, etc.). • Surfaces should be watertight and manifold, ready for slicing in Bambu Studio. • Export the model in STL or 3MF format, with both halves aligned and keyed (optional alignment pins or flat joining surfaces). • Avoid unnecessary internal geometry, keep walls solid except for the hollow
