I built this from plans (101 Best Ever Workshop Projects 2011). It provides storage, workpiece support, and a solid base to clamp the jig to the bench. It is made from a single 2’x4’ sheet of 1/2” birch plywood from the home center. The dividers are dadoed into each other but not into the base, just glued down. There is a minor problem in that I have a newer version of the jig that is a bit larger so it hangs off the back. The catches came from Lowes. I was lucky to find them there because the ones called for in the plans were from a mail order catalog. And that can get spendy on shipping when ordering just one item.
