3D Topographic Map of Beijing STL Model for CNC & 3D Printing

A highly detailed 3D topographic relief map of Beijing, capturing the immense scale and legendary concentric ring-road layout of China’s historic capital. The model masterfully renders the structured rectangular core of the ancient city center, dynamically surrounded by the sweeping lines of Beijing's famous massive Ring Roads. Features include an incredibly dense web of urban avenues, radial expressways, and the rugged, expressive mountainous terrain hedging the city basin from the north and west. The mesmerizing contrast between the strict imperial geometry of the urban grid and the organic mountain ranges creates a stunning modern look with a beautiful play of light and shadow. This 3D wall art is perfect for premium interior design, office decor, and custom high-end gifts.

TECHNICAL SPECIFICATIONS:
• File Format: .STL (clean, manifold mesh, optimized and error-free).
• Recommended Default Size: 305 x 305 mm / 12" x 12" (1:1), easily scalable.
• Total Stock Thickness: 15.9 mm / 0.625" (optimized for standard 5/8" furniture panels).
• Relief Carving Depth: 2.5 – 3 mm / 0.1" – 0.12" (ensures clean details without wood chipping).
• Backing (Bottom) Thickness: ~13 mm / 0.5". The solid base guarantees high rigidity, preventing the wood from warping due to humidity. Ideal for milling hidden keyhole hangers on the back.

PRODUCTION RECOMMENDATIONS:
The model contains thin lines, intricate street grids, and complex urban layouts. To achieve a flawless result, we recommend using high-quality tapered ball nose mills with a small tip radius (0.25 mm to 0.5 mm) or V-bits for fine engraving and finishing.

Perfect for carving from dense hardwoods (oak, beech, ash, walnut) or homogeneous materials like MDF, acrylic, artificial stone, or for direct 3D printing.
