A big but somewhat flat box with removeable inlay that can be used to take your favorite (un)healthy snack with you when going on the road. Should fit nicely in a backpack. 

The inner size is 220x170x40 mm, the inner tray is available in 35mm and 40 mm height – both fit inside. 

Print the latch twice and use M30x30 mm screws for assembly. Print one of the tray versions – the 40mm version may a bit tight on height, but may also better keep the content seperated. 

I do not provide the FreeCAD files for this models, as those are still somewhat chaotic, and were created using a developer Version of FreeCAD (which is not compatible with previous versions). If there is interest in the files, I can provide them after the release of FreeCAD 1.0 (which should be pretty soon), as I can then prepare them with a compatible stable version. (Files are not compatible with 0.21.2).
