compass rose 3d model

Convert the flat image of the compass rose into a highly detailed 3D model. Reconstruct the geometry so that the central star has sharp, defined points with realistic thickness and bevels. Extrude the arrows and circular outlines with layered relief, giving them volume and smooth edges. Ensure all parts (star, arrows, circles, and letter N) are fully modeled in 3D as solid objects, not just flat extrusions. The model must be watertight (manifold) and optimized for 3D printing, exported in STL format. Make the design look professional and symmetrical, as if it were a real medallion of 8 mm thickness, with a base disk and raised details.
