architectural sculpture 3d model

Generate a solid 3D printable architectural sculpture. Overall size: 100mm height, 60mm width, 30mm depth. Base: 60mm × 30mm × 6mm thick, perfectly flat. Main body: a vertical rectangular prism extruded from base. Front face: replace flat surface with a single continuous cylindrical arc surface. The curve is defined as a circular arc with: radius = 120mm arc angle = 18 degrees total sweep arc centered on a vertical axis running through the midpoint of the model width The curvature must be concave inward (hollowed impression), not convex. Side walls remain perfectly flat and perpendicular to base. Top edge follows the same arc profile as the front face. All edges filleted with radius 1.5mm for printability. Fully watertight manifold mesh, minimum wall thickness 1.6mm. Optimized for FDM 3D printing.
