valley lily lampshade 3d model

Create a single realistic lily of the valley flower (Convallaria majalis) designed as a 3D-printable lampshade. Overall height: exactly 17 cm. Create only the individual flower head — no stem, no leaves, no branches, and no other flowers. The flower must have the characteristic bell-shaped lily of the valley form, with gently curved and slightly flared petals. The flower must be completely hollow inside. At the bottom/base of the flower, create one circular hole with an exact diameter of 5 cm. The hole must be centered and completely open, allowing a light bulb socket or cable to pass through. The 5 cm dimension refers specifically to the diameter of the hole, not the diameter of the flower base. Use a uniform wall thickness of approximately 2 mm, suitable for 3D printing. The model must be watertight, manifold, and free of unnecessary internal geometry. Keep the flower realistic, delicate and elegant while maintaining clean geometry suitable for 3D printing.
