A subdividing bin that fits neatly inside of the Plano boxes distributed in high volume, great for small hardware. Plano 3700 series and more. When using small parts, it's great to remove them without scooping out each part. First iteration is 16cc, adding mass at the base and making easier finger-reach.

As always: it's parametric, printable without supports, and exemplary design file for beginners to use as example.
