round fantasy shield 3d model

Create a highly detailed, 3D-printable round fantasy shield based closely on the reference image. The shield must be perfectly circular and symmetrical when viewed from the front. Preserve the central design with exactly 8 large radial pointed blades/spokes arranged evenly around the center. Do not reduce the number of spokes. Add a small raised circular boss in the exact center. Recreate the layered concentric rings, raised metallic borders, recessed textured panels and the embossed rune-like symbols around the outer rings. Keep the overall design clean, sharp and ornamental, but make all details thick and deep enough for FDM 3D printing. Create the shield as one single solid, watertight manifold object.

Minimum engraved depth: 0.8 mm. The front should be slightly convex and richly detailed. The back should be simp
