Stackable/Foldable Storage Crates - 3 Sizes System

These foldable crates come in 3 sizes, such that they can be stacked in different combinations, so that every crates' size is half that of the last.
This is achieved by following the DIN system where every crate has a length to width ratio of 1:√2.
The ultimate sizes of all crates was determined by the maximum bed-size of the printer (minus some safety margin).

 

The crates can be interchanged and stacked in the folded, as well as in the deployed shape.
They come with an easy to operate click-spring latching hook which makes opening and closing the crates easy.

 

I've added single-color, as well as colored versions, so that a lot of combinations are possible.
Also, the bottom and sides have areas of infill which can be changed to your own preference, see the images for examples of that.

 

Assembly is easy, no need for extra parts, fasteners or glue etc.
Just push the eight pins into their respective holes until fully seated and you're done.

The crates are sturdy, stable and can support significant weight.

===  Edit 15-10-2025  ===
I've finally found time to add the 'missing' colored version of the big crate.
It works the same as with the other sizes.
Thanks to @auroralee and @Dendrowen for pointing this out (some time ago).
I'm sorry it took so long, a lot has been going on.
Enjoy.
