I made this for my work desk because I couldn't find something that I wanted. The grommet hole is meant to have cords come from beneath the desk, but most of my cords were too short to go from the wall, all the way down below the desk, then back up through the hole, and then be able to plug into something in the middle of the desk. Then there are some cords that I am not using all the time, and I needed to just sit there where I could get to easily, and so I made this. So far, it has worked really well for me, and I made it so that I could replace the hooks if any of them happened to break. 

Hope that it can be helpful for someone else!
