Any old box should do. I picked this one up at the thrift store for a buck. I think it was a silverware box. The main thing I wanted to show here is the grommets I Found at the hardware store. The project itself doesn't differ much from the others on here, but the grommets were a nice touch to finish it off and help hold the cords with their "gripiness".
Step 2: Prepare the box.
I tore out the beat up green felt that lined the box. I then removed the lid and laid out the the grommets to mark the holes. I did this on the inside to avoid marking up the top.
Step 3: Drill the holes
I first drilled a pilot hole through from the under side on my marks, then I turned it over to drill from the top with the spade bits. I had two size grommets, one required a 3/4 in. hole, the other a 7/8 one.
Step 4: Insert the grommets
I found it made it easier to use a little soap in the groove on the grommet, they are made to fit tight.
Step 5: Assemble
I drilled a 1 inch hole in the back corner of the box, the sides are thicker than the top, so no grommet there. I passed the plug from the power strip through the hole(tight fit) and plugged it in. My MP3 player charges through usb so I ran that through the power cord hole as well. I plugged the remaining power supplies in, wound up the excess cords, and threaded them through the grommets.
Step 6: Close the lid
Now all thats left to do is to plug in your devices and enjoy your tangle-free desktop.
