The prompt
Create a 3D-printable lighthouse-shaped digital alarm clock, about 180–200 mm tall and 115 mm wide. Include: - A front opening for a 1602 LCD display (80 × 36 mm). - Space inside for an Arduino Uno R3 and wiring. - A mounting point for an SG90 micro servo under the roof. - A 5 mm LED in the top as a soft night light. - A 45–50 mm speaker inside. - A removable roof and back cover for easy access. Make the design sturdy, simple to assemble, and suitable for 3D printing. Keep all components in separate parts where necessary. Export as STL and STEP files.
