Hey there, wonderful people!
I got half way through explaining why this wouldn't work, and then realised that I could indeed make it work! :D
This design may well look familiar! Yep, the Colossus Vault and the Vault Box are the ancestors of this, but they differ in a key way. You see, the Vault Box has a lid separate to the box itself, specifically so that the box can have a flat base. The Colossus Vault, on the other hand, has a hinged lid, but prints upside-down to accommodate that, which means the box base ends up angled, and thus needs to be huge!
The question posed to me was: could we have the flat-based Vault Box, but with a hinged lid?
My first thought was: Nope!
But that didn't last long...

It's the best of both worlds! So, how's this achieved?
Well, you may recognise the hinge style here from the Saloon Box. It's an approach that allows the lid to print upside-down on the bed and swing up externally to fit on top of the box. Was the Saloon Box the first time I used that approach? I'm not even sure! It's a hinge design I'm exploring right now for new, asymmetric versions of the Clamshell Cases, so it was at the front of my mind, and solved all my problems!
I did of course have to modify the box rim to accommodate the rotating lid, but the actual usable interior space remains unchanged.
The end result is the best version of the Vault Box concept yet! The big, chunky hinges are quite satisfying to use, and who doesn't love a nice hinged lid?

Printing Tips
The model prints with the lid open and the box base-down, like so:

This is an articulated design, so as usual watch your bottom layer quality, and watch for any printing issues like stringing or overextrusion that bind moving parts together!
It's a fairly wide design and might push the limits of dimensions on some printers, but thankfully it scales down reasonably - the grey one in the photos was test printed at 80% on an Ender 3.

Final Thoughts
Well, I didn't expect I'd be returning to this model, but I'm glad I did, since the result is a much more elegant, practical version of the Vault Box idea than its predecessors!
Enjoy!

Sven.
