The prompt
> **Design a professional 3D CAD model of a compact smart electronic safe. The safe body and the door must be two clearly separated components. Make the door significantly thick because ALL electronic components must be mounted inside the door, not inside the main safe body.** > > **Door-mounted components:** > - 0.96" OLED display on the upper front area > - 4×4 membrane keypad below the OLED > - RC522 RFID reader positioned below the keypad > - Green and red status LEDs > - Buzzer > - Internal mounting brackets/standoffs for the STM32 NUCLEO-F411RE and ESP32-WROOM-32D > - Servo motor and mechanical locking mechanism mounted inside the thick door > - Cable channels inside the door to keep all wiring organized > > **The main safe body must remain completely empty internally**, providing a clean storage compartment for the user's belongings. Do not place electronic boards, batteries, sensors, or wiring inside the storage compartment. > > Design the door as a **thick electronic door panel** with an internal electronics cavity behind the front panel. The electronics should be accessible by removing an inner service cover, while the external front surface remains clean and professional. > > Include: > - Strong mechanical hinges > - Servo-driven locking mechanism > - Mechanical latch/bolt extending from the door into the safe body > - Proper screw holes and mounting bosses > - Cable management channels > - Ventilation openings only where necessary > - Rubber feet at the bottom > - Rounded edges and realistic manufacturing details > - Realistic wall thickness suitable for a small prototype safe > > **Overall appearance:** professional modern electronic safe, compact, clean industrial design, suitable for a university embedded-systems project. The design should look like a real commercial product rather than a simple box. > > **Important:** Keep the storage compartment completely unobstructed. All electronics must be integrated into the thick door. > > Create the model as a **fully assembled 3D CAD design**, with separate parts for the safe body, door, inner door cover, hinges, locking mechanism, mounting brackets, and electronic component holders. Include an exploded view showing how the door electronics and mechanical components are assembled.
