Ultimate Clock for Hostel

I had already made a clock project for class room (Features: -Time | Countdown Time | Temperature --on Dot Matrix Display(MAX7219) -Countdown Timer for when class will end -Buzzer to buzz 5min before Class ends -Subject displays for few seconds when that class starts) I now wanted it to control an AC buzzer (for my hostel for wake up time, prep time, quiet time) and today i soldered female pin to arudino PCB board that I made for the relay module and then I measured the sides to 3d print the encloser ( my first time 3d printing something) Wish me luck!
