The prompt
Create a professional parametric 3D-printable handheld electronics enclosure with a SEPARATE removable lid. **Enclosure:** 90 × 70 × 30 mm **Wall:** 2.5 mm **Bottom:** 2.5 mm **Lid:** 2.5 mm **Lid clearance:** 0.25–0.30 mm **Electronics:** - Arduino Nano inside, PCB approx. 45 × 18 mm - 1.3" OLED, module approx. 35 × 34 mm - OLED lid window: 30 × 17 mm - Mini buzzer: Ø10–12 mm - Buzzer sound hole: Ø8 mm - Mini SPDT switch on right side, opening: 11 × 6 mm **BUTTONS — NO JOYSTICK:** Use 5 tactile push buttons: - 1 center button - 4 buttons around it: UP, DOWN, LEFT, RIGHT - Use common 12 × 12 mm tactile push buttons - Button hole/opening: approximately Ø8 mm or suitable for the selected button - Arrange them symmetrically like a D-pad/control layout - Keep 5–7 mm spacing between buttons - Create proper internal button supports. **LAYOUT:** - OLED: upper center - 5 buttons: lower center - Buzzer: upper right - SPDT: right side wall - Arduino Nano: inside/rear - Leave enough space for wiring. **LID:** Create the lid as a completely SEPARATE body, not attached or hinged. - 4 × M2.5 screw holes in lid - Ø2.7 mm clearance holes - Countersink screw heads - Base has 4 matching screw bosses - Boss OD: 7 mm - M2.5 screw support - Use M2.5 × 8 mm screws - Show lid separately above the base in exploded view. Make all dimensions parametric, components collision-free, USB accessible, FDM-printable, and professional. Create BASE and LID as two completely independent parts.
