Rolling work table

This is a rolling workbench/table I designed for my own personal use. I needed something which would be sturdy enough to hold tools and car parts on while I work on cars. The design is intended to be made from a single half sheet of plywood (4' x 4') and made with just a circular saw and drill. It features a small light on the top for working at night, tool holder, and electrical panel for testing of components. The bottom section has a solid floor which can house a large 12v battery to go with the upper section and 4 casters for easy maneuvering.
