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.

This design uses Gridfinity Rebuilt for the bins and most of the drawer design.
