Stackable storage boxes, box-in-box (small, medium, large)

Stackable storage boxes with honeycomb profile to save material.
Note that I created 2 different series, which vary in how they much they stack on top of each other and if smallers sized boxes can fit in a larger box. Below you find the differences and the links to the right series.
First series: this model represents this series - Stackable boxes, box-in-box (small, medium & large) :
- Stackable: yes, but only boxes that are the same size (see pictures)
- Box in box: yes, 2 small boxes fit into one medium box, 2 medium boxes fit into one large box (see pictures)
Second series: Fully stackable boxes (small, medium & large) :
- Stackable: yes
- Box in box: no

Included in this model are 3 sizes of storage boxes:
- Large: 250 mm length x 250 mm width x 129 mm height, 2.5 mm wall thickness and 325 grams filament usage
- Medium: 239 mm length x 119 mm width x 122 mm mm height, 2 mm wall thickness and 187 grams filament usage
- Small: 114 mm length x 108 mm width x 115 mm mm height, 2 mm wall thickness and 103 grams filament usage
The boxes are stackable in multiple manners:
- Two boxes of the same size can be stacked on top op each other (small on small, medium on medium, large on large)
- Two small boxes fit in one medium box
- Two medium boxes fit in one large box
To get you started, in the 3mf file, there are 3 plates:
- Plate 1: the large stackable storage box
- Plate 2: two medium storage boxes
- Plate 3: two small storage boxes (4 fit on a plate)
All models can be printed without any supports. Feel free to print it and let me know if you have any feedback.
