military emblem 3d model

3D model of a military-style emblem badge, optimized for metal casting and minting. Central prominent element is a bold, solid number '8' with sharp clean edges. Surrounding elements include quadcopter drones, a stylized globe grid, and lightning bolts, all tightly integrated into a single cohesive badge. The entire model must have a completely flat and solid back surface (backplate) for badge attachment. All details must have a clean, solid, manifold geometry with closed volumes, positive drafts (tapered edges for mold release), and no hollow spaces or floating parts. High-relief design, thick structural connections, smooth metallic finish, hard-surface modeling, low polygon count with clean quad-dominant topology suitable for CNC manufacturing.
