Large Monitor Back Organizers

I remade this organizer because I had all this wasted space behind my monitor I wanted to use. The original was far too small for what I wanted so I just added some interior dividers and made it longer and taller. I have 2 versions; one is long and deeper about 100MM. The second in about 330MM long but the compartments are about 80MM deep. I use one of each on the back of my monitor and it gives me an enormous amount of good usable space.
