Hello everyone. Here is my version 2 of the Vault that I made.

This version is way way better and 100% working. Untill now in  my tests it works flawlesly.  

Huge thanks iordanflorin92 for the rachet mechanism 

M3 screws needed about 5-8 mm lenght should be enough. There are 6 screws for cap, 2 M4 screws for hinges, and 4 more for the back cap so in total would be 12 screws

Watch the clip to see it in action 

Here is a quick assembly video :
