I like to use steel Durham MFG Bins around my shop and home for storage of small parts, hardware, tools, etc. They come in two sizes, Large and Small and have various inserts from the factory. I realized there was a lot of empty space when using small hardware so I wanted the option of having stackable bins in different compartment sizes. These bins are designed to work with the Small bins and are broken up into 1/2, 1/4 and 1/8 sizes in several configurations. If you don't see a layout you want to use, let me know and I can draw it up.
If you decide to print the 2-Part Tool Tray, you will need four M3x20 Socket Head Cap Screws to pin the halves together.
Print them at 0% infill with the thickest layer you can. I did these at .3mm layer height and they were quite economical.
