Hello, here is my small project that became pretty big, it started as a quick swap for my broken earplugs container.
Then I wanted to make it opened by left handed or right handed people, then to open with one hand, then there been so many prototypes that it would be good to make storage for them, then it would be good to make this storage modular etc :)
SO!
3 box types, small ones and one that is taller. Small ones are divided simply by thickness of bottom layer (0.2mm-thin and about 0.8-thick one), if you use transparent plastic then you can somewhat see whats inside if you print thin one. For everything else I suggest Thick one as its more robust and you simply wont see anything with any other type of plastic.
Storage for those boxes is pretty interesting, it can be assembled in any way, tall towers, or square shape.
So have fun :)
