glass ornament 3d model

Create a 3D spherical Christmas ornament. The ornament must be a hollow sphere with two flat circular faces on opposite sides (front and back). On each of these flat faces, extrude the IATA-CSIC isotipo logo in relief, keeping the original colors and proportions. The rest of the sphere should be smooth and neutral. The logo relief should be clean, symmetrical and centered on both faces. Provide the model in STL and OBJ format, optimized for 3D printing. Maintain the original logo colors as vertex colors or textures.
