I got a ton of used stackable storage boxes from a friend so I've been looking for a cheap way to mount them in my shop.
I had a bunch of old license plates lying around, turns out they're quite suitable for this purpose.
You only need a bench vise or a joggling tool (I hope that's the correct translation).
It's my first instructable, so bear with me ;)

Step 1: Preparing the Plates
Simply use the tool to shape the edge of the plate so you can slip on the boxes.
Alternatively you could just use the vise to flatten the plates' edge (depending on how your plates look like) and then use spacers (i. e. nuts) when bolting it to the wall.
Step 2: Mounting the Plates to the Wall
...yeah, do that ;)
And then just fit the boxes. It's quite sturdy as well.
If you want it to look more neat or don't have enough plates, you could cut the plates in half horizontally. That way the boxes would hide the "mounting".
