3d insulin pump cover

Create a precise 3D cover for an Omnipod insulin pump. Dimensions: 39 mm (W) × 52 mm (L) × 14.5 mm (H). Shape: rounded rectangle with ~8–10 mm corner radius and convex top (~1.5–2 mm curvature). Wall thickness: 1–1.5 mm. Include bottom cutout for adhesive area (~70% underside) and side clearance for vents/sensor. Fit: snug, tolerance 0.2–0.4 mm. No sharp edges, skin-safe, lightweight. Design: Voronoi pattern mapped to curved surface. Cell size 3–6 mm, slightly irregular, avoid micro details. Depth variation 0.3–0.8 mm (engraved or embossed). Visual: soft pastel gradient (lavender, teal, blush), subtle shading to emphasize curvature, calm and elegant. Output: high-res 3D model + render, top and angled view, manufacturable (3D print ready STL).
