I've seen all the storage options. Gridfinity, milk crates, threadboards, multiboard, etc. They are all awesome. I just needed a big box I could set on a shelf and be able to clearly see what was inside of it. Oh and I wanted it to stack. That's all.
I also wanted an option where I could purchase some plexiglass off Amazon, make a single cut, and have it fit into the boxes. Then Just a few dabs of CA glue in the groove to secure the plexi in place.
This is a design I made for myself that I'm must making public. If you want to download the drawing and tweak it to your liking, the STEP files are included.
