I like how you numbered them so you can avoid the whole round peg - square hole problem.
I have a ceramic jar in my kitchen that I use for spatulas, wooden spoons and the like. Try to pull out one and you get about seven. If you're lucky, not fall on the floor. This idea would be good for something like that. It would be even better if there were slots so you could just pull them out instead of lifting them out. (If I had something like that, it would have to mount above the splash guard and then I would run into the problem of bashing them into a cabinet if I had to lift them out.)
