LEGO Safe With A Working Combination Lock - Whoa

Hey Lego fans. Step up your game!
"LEGO builder Jason Allemann has proved that 3-number combination locks aren’t that complicated, and a few carefully assembled LEGO bricks are enough to create one.
It’s a pretty smart build as you can see in the video, designed to be impossible to take apart without knowing the combination... or without using a hammer.
Time to hide those rare minifigs."
