I bought this(https://www.amazon.com/gp/product/B000LDH3JC/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1) thing of tiny drawers on Amazon to store metric screws, wires, pins, etc. for 3D printing. Only thing was that it didn't come with very many dividers for the drawers, so I made this so that I could just print some more.

Made in Tinkercad. Here's the link if you want to modify it.
