The box to the left is for Lathe Accessories. it contains my tail stock, tool rest, centers, and an old set of chisels my father left me twenty years ago.
In the center is a box to hold my drill press accessories. It contains drill bits, chuck and key, and a circle cutter.
On the right is just a block of wood that I drilled to hold my saw blade arbors.

When not needed these all store snugly in the leg braces I'd added earlier. I also added a jig that securely holds my saw fence when not in use on the left. The top of the boxes, when in their storage location, also create a little shelf.

The Blade Insert is missing in this photo because it is being painted.
