3d printable case

Design a 3D‑printable two‑part case: a top shell and a flat bottom plate. Use millimeters. The case is pill‑shaped (rounded rectangle). Total outside dimensions when closed: 200 mm long (X), 80 mm wide (Y), 35 mm tall (Z). Wall thickness is 3 mm everywhere. All four vertical edges have a 10 mm radius. Part 1 – Top Shell: A hollow shell, open at the bottom. Outer box: 200 mm × 80 mm × 30 mm tall. Apply 10 mm fillets to the four vertical edges. Subtract an inner cavity box 194 mm × 74 mm × 27 mm tall, positioned so it leaves 3 mm walls on all sides and a 3 mm thick top wall. The bottom remains open. Top Face Cutouts (origin at top‑left corner of the top surface, X to the right, Y away from front edge): 1. Display window: a through‑hole rectangle 66 mm (X) × 16 mm (Y), centered at X=100 mm, Y=70 mm. 2. Left touch recess: an oval depression 60 mm wide (X) × 40 mm deep (Y) × 2 mm deep into the surface, centered at X=45 mm, Y=40 mm. Do NOT cut through. 3. Right touch recess: identical oval
