Making a 3D Printer - Control Box

I made a box out of MDF to house the electronics for my 3D Printer. I started with some rough sketches, cut the 1/2" MDF on the table saw and then the 1/4" on the laser cutter. Here's what I've got so far: 

 It took a lot of trouble shooting to get the alignment just right. 

Both of the sides slide out for easy access to the electronics. 
Eventually I will paint the box after drilling a few holes in the top for the cords to go through.
