Modular Tool Corral

It's here! The world's first easily customizable, inexorably modular, supra-comestible,
mobile tool corral. And it's cheap.
A small, $12 furniture dolly is at its core. I chose 2x4 framing because it is cheap and gives me a surface to mount just about anywhere easily with cheap drywall screws. This suits my purposes and gives me a specific place to put each tool. Tools tend to clutter my workspace and then elude me when they are needed most, so I am trying to fight back with a bit of making.
