Moulin Roty 3 slots story box

I didn't know much if something like this existed before. I built this with the idea to create a shelf with modular colors to make it playful, that's why i kept this model small. I wanted something that can hold the discs upside down without having to build a lid with a hole to hold them. The disc “clamp” design uses less material in that regard, and holds the discs perfectly: not too soft, so you can shake the unit and no disc would even pop, and not too hard so it's not difficult to pick one, and you can “roll” the disc, which is quite satisfying (for fidget lovers).

They can hold 3 stories, which is how the extension boxes are sold in moulin roty website but i'm sure it could be extended to 5 easily ; i just don't know how to build parameterized models in onshape (which i use for modeling).

Dimension is 4x3x2.4 (cm) and prints with no support (I didn't have a single failure while printing 12 of them)
