FOSBOS is a completely free organization system, each model is open source, I have included the Fusion 360 file and the 3mf file.
Since I have not yet found all the formats of empty containers I needed, I have simply redesigned the missing ones and attached the Fusion 360 file and the 3mf file.
These models are containers for storing loose items that fit into drawers with a maximum height of 10u.

Many thanks to @Asdfgasdfg and @Adamko for the great open source implementation.
