Laser Cutting ~ Gear Box

In order to remove the lid from this box, you must turn the crank. The gears will spin and the lid will slide open. Yes, it's rather ridiculous, but I find it soothing to crank the lid open and closed...

!!! New UPDATE !!!

This is an Arduino-powered version with an integrated stepper motor. The initial switch press turns on the internal lights and rotates the gears, and slides the lid open. A second press of the switch turns off the lights and closes the lid.
