Stacking bins

I made some "simple" stacking bins for my wife's sewing things (like little clips and pins and whatnot). Very clean design, easy to print, easy to use. Includes two sizes -- one about 4" on a side, and a 1/2-size version so 2 small ones can stack on the larger.

I made a more sophisticated (and boxier) part for my own garage use. This design is modular, I can blow them up pretty large. Smaller generations will stack 2-per-layer on the next larger size. Each size includes a matching "lid" if needed, though realistically I'll probably only use the lid for the smaller sizes.

I've only made 1 depth (about 2cm + the ledge) but can fire up deeper models if anyone needs.
