delegacia policial 3d

A realistic HO scale (1:87) Brazilian urban police station building, two-story structure with a flat roof, designed for model train diorama. The building features painted concrete walls in beige and white tones with blue tile accents, a centered entrance with a small canopy, and a sign reading "Polícia Civil" above the door. Include rectangular windows with dark frames, external wall-mounted air conditioning units, and subtle weathering. On the right side, add a small garage with a metal gate suitable for a police vehicle. The roof should include simple details like a water tank and antenna. The geometry should be clean, simplified, and optimized for 3D printing (STL), with slightly exaggerated details for small-scale visibility. Ensure proper proportions for HO scale (approx. 12 cm width). No interior needed. Focus on solid structure, printable walls, and minimal fragile elements.
