This is a wood working group. I had the luxury of some good solid wood bookcase shelving built in. The sections were roughly 48 wide with 3 sections roughly 12" tall each. This stuff was and is all utilitarian - it ain't pretty or fancy.
I subdivided the spaces with some scrap horizontal ply making 3 spaces in the top and middle sections and a vertical break at mid point to stiffen the shelves. I made boxes from scrap - 1/4 stuff for the sides, 1/2 for the bottom and ends with some additional blocks in each "drawer" to create smaller spaces. The drawers are about 2 1/2 tall, 4 wide, and 12 long. I did belt sand the outside corners to make them easy to hold. I have used MDF, ply, and wafer; they all work well/ This stuff is shot together with staples, and if something starts to wear out they sure are easy to remake. The bottom section of the book case requires bending over, so avoided like the plague; but it is just right for dairy cases (of course I bought them ).
The top left box has 1/4-20 nuts, spacer block, 1/4-20 washers, spacer block, lock washers, spacer, anything odd that is 1/4-20 like wing nuts, couplings, nylox, etc. There are 5 boxes total for 1/4-20, each subdivided into various lengths of bolts. Number
4 is divided only into mixed flat head and machine bolt. Number 5 has carriage. Repeat row 2 for 5/16 Row 3 for 3/8

Right hand top section. Same boxes split at mid point. Coarse 1 1/8 drywall / fine 1 1/8 drywall C 1 1/2 / fine 1 1/2

2 1/2's
3's
The rest are filled with hex drive screws, self drilling, fender washer, square drive, etc Write what they are on the ends of the box. If it changes, swap ends or sand it again.
I did acquire a really nice card index from a library. Nice wood cabinet with high grade plastic drawers. I had a neighbor who used LOTS of medicine who collected prescription bottles for me. Make sure they are clear or yellow so you can see what is in them, the blue or white ones suck. One drawer for air fittings, one for electrical testers, replacement blades, etc I have one small bread pan, like for a rum cake, full of all those mixed nuts, bolts, fine, coarse, long, short, hex, square, phillips, straight, flat, pan, hex mixed hodge podge for everything smaller than
1/4=20. Larger quantities of any one thing get a pill bottle, but the bread pan gets used every day. Make a spill tray to dump it out, search, return to bread pan. Everyone needs a Junk fastener bucket.
Hope this gave you a few ideas.
There are other sections of little home made drawers. It is always a work in progress. Quit worrying about exotic cabinet grade work, just create something that works, works well, and doesn't scream - oh, don't scratch me!. Don't have so much time or material invested that you wouldn't be willing to toss for a better idea.
