SMT component bulk storage cabinet

I designed this storage cabinet for organizing SMT components in my workshop. It uses Gridfinity bins with shelves that are a Gridfinity base with magnets. The design is open source and at https://github.com/chl33/SMD-Gridfinity. I discuss this storage system and some related designs in my blog post about hobbyist PCB assembly with SMT components: https://selectiveappeal.org/posts/smd-assembly/. The shelf needs to be printed with supports for the drawer-slide guides on the sides. I printed everything in PETG. I apply a little epoxy to the front of bins to help labels stick. Otherwise the cylindrical shape of printed layers provides little surface area. I screw M3x5 screws into the bottom of the bins, and press 6x2 neodymium magnets into the spaces for them in the shelves. I find I can make a stack of the magnets, set the stack over the hole, and whack the top of the stack with a rubber mallet to get the magnet to be seated in place. Then move the stack to the next location.
