Lightweight Stackable Small Storage Bin/Box (Customizable)

This is somewhat an experiment on how lightweight I can make a bin that is still useful for storing electronics widgets (the default size is plenty for arduinos or such).

I think it also ended up somewhat stylish and "see-through", but that might be subjective.

2021 update: Now option for floor made of triangles; customizer has more freedom in the depth of the window cutouts
