Render a high-fidelity 3D prototype image of a smartphone case with a secret, ultra-thin compartment built into the entire back of the case. The case should appear sleek, minimal, and flush with the phone — the compartment is not visible from the outside when closed. It includes a small latch or sliding mechanism that allows the bottom portion of the case to open and reveal a hidden slot designed to hold a thin object like a sheet of pills, or folded note. Show both closed and open versions, highlighting the discreet nature of the compartment. Use a white or soft pink case with orange accents to indicate the hidden mechanism. Include side and bottom angles to show functionality See more
