Despite the small wall thickness, it is quite stable because of the integrated bracing. In addition, it is printable without retraction.
If "fhs, floor height (solid)" is set to zero, you will probably see some warping at the corners....find them on the photos ;-). Thats why it is better printed with one layer of solid floor.
The number (and position) of dividers can be configured in Customizer and a label holder can be attached to the front.
Filament usage for a 65x150x40mm box (with one divider) is 39g / 5m and it takes about 2:30h to print (@my printer/configuration).
