Modular sorting case with removable storage boxes that lock into place when inside the box. The boxes fit into a grid pattern that is both on the bottom and in the lid which prevents the storage boxes from moving around and prevent them from "leaking" parts. This box design was inspired by Alexandre Chappel's Assortment case (https://www.alch.shop/shop/p/assortment-case) (https://www.youtube.com/watch?v=VntGnLuwoeY)
The boxes fit into a 45mm x 45mm grid array, and each size increments by 45mm. Every possible size for a box is provided. The internal volume of a 1x1 box is 42.1mm x 42.1mm x 57.8.
