wine bottle shelf 3d model

Create a 3D model of a freestanding shelving unit shaped like half of a wine bottle. The object must be a solid 3D volume (closed mesh, not flat, not a surface). The shelving unit is tall and vertical, with proportions similar to a large floor-standing wine rack (height about 2 meters, width about 80 cm, depth about 35 cm). The silhouette follows the profile of a wine bottle: wide base, curved body, narrow shoulders, and short neck at the top. The back side is flat, the front side is open. Inside the structure, add multiple horizontal shelves, slightly curved, evenly spaced from bottom to top. The structure is made of black painted metal, thin but strong, with a modern and minimalist design. The shelves are empty (no bottles, no objects). The geometry must be clean, manifold, and watertight, suitable for export to OBJ and import into SketchUp via Transmutr. Style: modern, elegant, high-end design furniture for wine shop or restaurant. Output: solid 3D mesh, ready for OBJ export.
