noah's ark 3d model

Create a 3D printable model of Noah’s Ark based on the attached image. The model should match the outer shape exactly — a rounded wooden hull with a curved bow and a small rectangular cabin on top. Include the door on the front lower section and the window on the back upper cabin. Keep the proportions, roof angle, and curvature true to the reference. Make the geometry smooth and clean, without surface textures or fine details. Do not add people, animals, water, or background. Ensure the model is watertight and manifold, ready for 3D printing (STL). Focus on accurate shape, silhouette, and structural form only.
