I designed a simple box in CAD where the lower part of the box, houses all the electronics. The top lid is hinged using a 3mm rod. Then changed the design for 3D printing. The material I chose here is PLA, 20% infill with 0.2 resolution. Also, the box can be made, out of Fam board or wood, if you don't have access to a 3D printer.

The code is simple. For the led strip, I have used the Adafruit_NeoPixel library. The pins can be changed, the led strip requires a PWM pin. The default timer is set to 5 mins, this can be modified in the code. You have to add a delay of 60000ms to add one min.
