I found this trolling Pinterest, awesome job! I would like to do the exact same thing you did. In fact, I have the same Milwaukee fastener organizers too and would like to store them as you did. How did you secure the plywood carcus to the underside of the bottom bracing? Those Milwaukee cases can get pretty heavy, so I'm sure you figured out a method to secure that plywood.
Since its been a while since you posted this, how do you like the table/set-up in hindsight. Would you do anything differently? Thanks!
