Plugs and Switches Travel Storage Box

I work on dusty, bumpy roads, and our plugs and switches used to get scratched or dirty when stored loosely in boxes.
So, I designed a box that holds 16 plugs and 12 switches, keeping them from touching the faces and getting marked up.
We've used these for almost 9 months — it works perfectly, and the box and drawers are still in great shape.
