I got the inspiration for this build from when Nick Ferry on YouTube had a shop organization project using the Harbor Freight parts bin storage units.
I did not have any vertical wall space to use and I felt that having to reach a little higher if they were in a stacked manner would not be convenient. Furthermore, the white wire shelf that I replaced always had the brackets in the way and never really was good at keeping somewhat unstable footprint items from falling.
Here is the finished product. I just need to spend some time labeling the parts bin so I don’t waste any time searching for the right bin.
The way I am going to label them is much easier than Nick’s method. 
I think he would appreciate it since he has a background in theater work. It is gaffer’s tape. The kind I have has an extremely strong adhesive with a cloth surface that a Sharpy really takes well to.
Here is the file for the Sketchup plan.
Please let me know what you think!
