Alex H sent in these storage tech tips and generously shares his CAD file for the rack he designed:
The above photo is the custom flat-pack storage rack I designed to hold standard shoebox-sized plastic containers. I’d previously kept them stacked 4-high, but getting at the bottom one was always a chore, and heavy bins on the top threatened to crush the ones on the bottom. Now, each has its own slot and is easy to access. The dimensions of the shoebox containers differs slightly by manufacturer, so if you make something like this, verify the dimensions of the style you’re using, and buy enough to fill the rack in one go.
I designed the rack to be cut out of ¼ in plywood on a CNC or laser machine, here

My second tip goes with the link above. My favorite 3D CAD software is a package called Onshape
. It’s industrial-strength CAD that runs completely in a browser, meaning no install, updates, or machine requirements, and it runs seamlessly across my PC, Mac, and Linux boxes. The company offers a free maker/hobbyist license, only restricted by all created documents being public.
