French Cleat Box for Harbor Freight Storage Bins

I have a ton of those yellow storage bins from the Habor Freight 20 bin storage case.  The ones everyone uses to make a “Sortimo Style” storage shelf.  I made a French Cleat box that can be used alone or hold these bins.

The cleat is for 3/4inch (18mm) plywood cleats.  I printed the pieces separately so they have to be glued together.  This was to the need for supports.
