globe 3d model

Create a small spherical planet with an overall size of exactly 120 × 120 × 120 mm (12 × 12 × 12 cm). The planet should have multiple distinct biomes across its surface, with each biome featuring its own unique textures and terrain details. Make the planet hollow inside to reduce material usage and printing weight. However, do not make the outer shell too thin, because it could become weak, fragile, or deform during 3D printing. Inside the planet, add a lightweight structural support system made of interconnected pillars and support beams. The supports should connect different areas of the inner shell to keep the planet strong and rigid while using as little material and weight as possible. Optimize the entire model specifically for 3D printing: - Strong but lightweight structure - Appropriate wall thickness - Minimal unnecessary material - No floating or disconnected geometry - Clean, manifold geometry - The final dimensions must remain 120 × 120 × 120 mm Export the final model
