“A modern Scandinavian-style lampshade with a rounded trapezoid shape and deep vertical wave grooves running smoothly from top to bottom. The lampshade should be hollow, seamless, and 3D printable, with a uniform 2 mm wall thickness and a circular base opening on the bottom with diameter of 188 mm. The surface should appear matte white plastic, minimalist, and clean.”
