ribbed vase 3d model

Create a realistic 3D printable model matching the reference image: an elegant rounded, egg/teardrop-shaped vase, wider in the lower-middle and narrowing toward the open top. Include a small circular base at the bottom. The vase must be completely hollow and open at the top, with a closed bottom. The walls must have two distinct surfaces/layers: the outer surface is vertically ribbed/canelado, with many evenly spaced rounded vertical lines following the entire curved shape; the inner surface is completely smooth and flat, with no ribs or grooves. Maintain a consistent wall thickness between the smooth interior and ribbed exterior. The ribs must be integrated into the vase geometry, not separate or floating parts. The rim should follow the shape naturally and remain open. Create a single continuous, watertight, manifold mesh suitable for FDM 3D printing. No handles, lid, side holes, decorations, or solid filling.
