portable device shell 3d model

Front face: a recessed rectangular window opening for a display, framed by a smooth raised bezel with rounded inner corners. The window is an empty cavity — no screen, no glass, no graphics. Just the plastic aperture. Top surface: a shallow circular indent, approximately 12 mm diameter, marking a touch-sensor area. Left and right sides: smooth, gently convex, with a faint horizontal parting line running around the body. Rear face: a circular grille of small perforations for a speaker, and a small circular hole for a microphone. Near the bottom edge, a rectangular USB-C port cutout. Bottom: flat, slightly recessed base with four small screw bosses at the corners and a narrow ventilation slot in the center. Material: matte grey ABS-like plastic, soft-touch finish, uniform wall thickness. Clean product-design geometry, manufacturable as an injection-moulded shell. Neutral studio lighting, plain background, three-quarter view.
