Here is my take on a sorting systems for bolts, screw, all your small bits and pieces.
The brackets that support the drawers are designed to be stackable, you can raise them as high as you need them to be.
The drawer itself it a tray made from the gridfinity template.
I include the 2 bins I've been using.
I printed them with 10% infill.
Not good with these descriptions, but feel free to contact me if something is missing.
