This is a remix of my own stackable baskets (version 1) 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))
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 "...V2s" for "straight". And the difference in filament usage is neglectable.(For even less filament, try version 1b of the old design with initial layers 0 and only to top layers)
The new version comes with the same sizes and l as the previous and can freely be mixed. (depth between 10 and 30cm, width: 10cm, heigth. 7.5cm). The red and blue one on the picture are version 1, the yellow ones are version 2. And as before you can stick a paper label to the front
If you have smaller objects which might fall through the bottom holes or have an uneven surface that might hook somewhere at the honycombs - stick to version 1 or new v1b.
If you'd like different sizes, write a comment

The larger baskets should be printed without skirt to fit on the build plate and the 30cm variant probably still needs to be rotated 45° to fit on the plate diagonally.
