Stackable Baskets (v2, "real" baskets)

This is a remix of my own [stackable baskets (version 1)](https://www.thingiverse.com/thing:4674657) I created about a year ago. Although I was quite happy with them, I thought I could save even a bit more on filament by making them "real baskets", i.e. having honeycombs everywhere including the bottom.

I also added fillets everywhere - doesn't really save much on filament, but can have a beneficial effect on stability because layers are slightly shifted against each other at the rounded edges.

Disadvantage of the new design: longer print times and larger model files (mostly due to all the rounded edges (fillet))

BTW: Latest models now also available at [Printables: Stackable Baskets](https://www.printables.com/model/1116174-stackable-baskets)

__UPDATE 2022-03-06:__ Although the filleted combs are very strong when the print is finished, some very narrow bridging is required during the print. It looks like some printers have problems with this, leading to broken combs. Seems to happen only when large baskets have to be placed diagonally to fit on bed. (Never had any issues with baskets placed normally).

__Therefore I created a complete set without fillets__, which seems to print easier. These models are called "...V2__s__" for "straight". And the difference in filament usage is neglectable.(For even less filament, try [version 1b of the old design](https://www.thingiverse.com/thing:4674657) with initial layers 0 and only to top layers)
