Voronoi Sleeve

Create a hollow decorative sleeve for 3D printing. Inner cross-section: rounded rectangle 124.4 mm × 100.4 mm, inner corner radius 15.7 mm. Wall thickness: 1.7 mm. Outer dimensions approximately 127.8 mm × 103.8 mm, outer corner radius 17.4 mm. Height of side walls: 194.5 mm. Bottom must be completely open. Top must be open, with only a continuous 1.8 mm inward retaining lip around the perimeter so the sleeve can hang from the top edge. The four side walls must form one continuous shell. Replace most of the solid side walls with large organic Voronoi openings, approximately 22–24 mm cell size, leaving rounded ribs approximately 2.1 mm wide. The cellular pattern must continue seamlessly around all four rounded corners. Make the cells irregular, soft, rounded and organic, not hexagonal or geometric. No bottom panel. No top panel. No internal solid body. No speaker model inside. Output a watertight printable CAD solid.
