It's a tool caddy type of frame that I built to get a little more organized. I can keep all my putties, clamps, brushes, sanding sticks, misc tools in the little shelves (angled upwards so nothing falls out), and then there are the little bays at the bottom that I added to keep other tools out of the way. I made the base a little thicker for stability and more storage room.

I'm going to add some arms to the light so I can slide it out and angle it as needed.
