five-point star 3d model

Create a flat planar 3D printable 5-point star model with sharp and well-defined star tips. The star corners must remain mostly straight and geometric, only very slightly rounded (maximum 1 mm radius). Overall size: 200 mm wide and 20 mm thick. Apply a shallow moon surface relief texture (lunar craters and bumps) only on the front face. The relief must not affect the outer silhouette or the star edges. The star must be hollow inside, with thin walls suitable for LED backlighting. Uniform wall thickness between 1.2 mm and 1.6 mm. Include a separate removable flat back cover. The back face must be perfectly flat and clean. Clean manifold mesh, watertight, no distortions, no melted edges, no soft sculpting. Export as STL.
