stone urn 3d model

Create a 3D model in STL format of a monolithic urn shaped like a vertical elliptical vessel. The urn should have a smooth, slightly bulging body with a narrow, pointed base. The top is rounded and features a small central conical bump, like an integrated lid. The surface must be uniform and undecorated. The object’s proportions should reflect an ancient, massive appearance, similar to a hand-carved stone vessel. The overall dimensions should maintain a height-to-width ratio of about 2:1. The output must be a closed solid suitable for 3D printing.
