I picked up some blueprint/architect's drawers last summer in lieu of a rolling tool-chest, and while the drawers are great, there is no internal organization, leading to a big jumble of tools after a while. Had some time, so used some spare 0.5" plywood and practised woodworking.

Was fun, and works great! Pretty simple, too.

(apologies for the blurry pictures, I think my autofocus was zonked by the cold)
