In germany, a "Nähkästchen" is piece of furniture used to store handiwork utensil. They are usually small to medium sized wooden boxes which open in a folding style, providing easy access to many small compartments. Even though those are exceptionally useful, they are somewhat out of fashion, even by people actually doing handiwork. As a result, they can be obtained pretty cheaply and easily on flea markets.
I got mine for a few Euros, five or less. It was a bit battered, one of the lids was replaced by a mismatching piece of plywood. But eh, that was easy enough to fix. Partly fix, i have no dark wood stain at hand, so its a bit light now.
Anyhow, usually Nähkästchen have many small compartments, but this not so much. Which was fine, as i could now print my own dividers exactly as i needed.
Although i actually (rarely) do some crude handiwork, i neither like it nor have that much supplies for it. What i do like and have a lot (depending on ones definition of "a lot") of supplies for is electronics. Thus, my Nähkästchen contains a lot less needles and twine than traditional, but a lot more pliers and modules. Buttons as usual, though.
I guess its all to specific to my parts and tools and Nähkästchen to be of direct use for other, but maybe one can derive some inspiration from it.


Top left, hand tools. Screw drivers, pliers, tweezers, spudgers and whatnot. The Screwdriver is a really nice (but stupendously expensive) Wiha branded one with small exchangeable blades. There is also a generic branded smaller one from Conrad (german electronics supplier) for tiny and odd screws. The little flask can be found on Ebay, this one is filled with a light oil. Rally useful these flasks. The Spudger is one famously seen on bigclive. Most pliers are very old restored ones from flea markets, except the side cutter which is a new Knippex one. There is a drill bit handle from Ebay and some drill bits. Its amazing how useful such a thing is. And some other bits and Bobs and Sues.

Top right, Modules. USBTiny programmer (not on picture), beaglebone black, several USB UART's, some Arduinos, ESP's and such, USB Type-C breakouts, displays, sensors and some fusselkram.

Mid and bottom left, Soldering stuff. Pinecil and tips, wire spools (3D printed), solder spools (printed too), shrink tubing, lighter, super glue, isoprop in a little flask.
Also at the bottom a neat Hioki pocket multimeter (pretty old), a cheap "oszilloscope", breadboard, jumper wires, pipe cleaners and stufff.

Mid and bottom right, Water and Power. The power supply is quite neat. USB A, supports QC3 and has a Buck-Boost converter. Good enough for most of my everyday needs. Can be found pretty cheap on Ebay and such. The USB Tester thing is from Fnrsi and somewhat expensive, but supports just about anything. Type C, Type A, Type B micro, QC, PD, and whatever. There is also a universal usb charger, another (simpler) usb power supply, many wires, plugs with terminal blocks and other stuff. The grey box is my small parts storage, see "Flohzirkus".


"Flohzirkus" was sometimes used in Germany to refer to the small part counter at a local electronics supplier, meaning "flea circus".
Anyway, the Box is 3D printed, has about a fifty drawers (a single shade of red) and about a hundred compartments. And holds a (nearly) full E3 resistor and capacitor set. Plus some of the most common transistors, diodes, led's and ic's.
