How to Take apart an Etch a Sketch

Before I built the mechanics for my laser cutter I was planning on using the etch a sketch since the pulleys where already there. I accidentally cut the wires while taking it apart, so I made it from scratch (much bigger too). But I figured I'd post this in case you want a small laser cutter and need to learn how to take apart an etch a sketch. It was a bit tricky. The tought part was trying to take off the case. What you need to do is to pry the red off of the black, not the other way around.
