I'm thinking today about disaster account recovery. My master password is literally the key to my entire digital presence, and I want to make a little box for safe, secret storage.

Question for you #CAD #design #3DPrinting and #engineering folks - how would you design a tamper-evident little box that you load once and can tell if it's been opened before? What mechanism could you use if it was 3D printed? I know serial'd stickers and zip ties exist, I'm hoping for a DIY makeable solution.
