A pegboard wasn't really an option for me, so I designed this "under the tabletop" solution. The design is based upon a 1" aluminum square tube which I bought at my local big box hardware store for $16.27. The parts snap on to the tube and can slide back and forth. Its designed to be modular. I didn't want to drill into the legs of the table, so I used velcro and zip ties to secure it to the table. DesignSpark files are included for your modification pleasure.
