I remixed as I had a different set of countersinks from China: [https://www.aliexpress.com/item/4000050405050.html](https://www.aliexpress.com/item/4000050405050.html)

I found that the hinge is a bit brittle (too tight) and the latch is too.

Included Fusion360 source and an STL with some embossed text that I didn't print.

I was going to add some magnets to keep the bits in place but the hex fit is tight enough and the inner height just about right that its not needed.
