This is a print in place box!
No need to assemble it, just print it and use it!
Please see the release video, there is some useful info, and a better look at the box in it:
You can find the more "authentic" but assembly requiring box inspired by the movie Mulholland drive here: https://cults3d.com/en/3d-model/game/mulholland-drive-box
Try printing the test piece first, to make sure you can print all the hinges and locking mechanism, if it doesn't work at first, try adjusting the "horizontal expansion compensation" settings in your slicer.
