_*Important Info*_: When I initially uploaded all the different sizes on Dec 04, 2020, something went wrong with the bottom chamfer only leaving the little feet to fit into the stacking frame. So the initially uploaded baskets weren't really stackable ! (If you already printed, you can of course still use it at the lowest basket) I have uploaded all models on Dec 05, 2020 again, _*if you downloaded before that, please download again*_ ----
Yet another set of stackable containers. You can find several different sets of stackable boxes on thingiverse, but many of them are for very small things only or use quite a bit of filament, so the DIY variant isn't much cheaper than buying some boxes.
Therefore I was looking for a compromise between size, stackability and minimal use of filament - stackable baskets of reasonable size. The largest one (30cm x 10cm) need only 100g of filament and of course no support. An due to the honeycomb structure and some stiffeners they are still stable enough.
I decided for 10cm wide and 7.5cm high boxes with different length, up to 30cm, which would just fit straight on a 30x30 cm print bed*). All sizes are stackable on each other. You can also stick a paper label to the front.
