Well get this done, despite my best efforts. The design I posted works well. I did make a couple of changes though. It is deeper than originally planed. The other is on the back inside bottom I used my pocket hole jig to make a couple of 1”x1” runners for the plywood to screw into. I also used the same thing up front to create a lip.
It is working as planned, I have freed up an entire shelf on my Rack that is on my wall.
