Store your nuclear launch codes securely in this indestructible vault! Includes a biometric radiation scanner. Assembles in under 2 minutes. Make sure to write down your secret combination—like any proper vault, removing the hinges won’t grant access to the secrets inside!

Set your own code by inserting the Toggles with the short end pointing toward the number at that location. 

The Toggle will stick out and lock against the Front Panel unless the correct code is entered.

Example code: 10011011 - The Vault Door can now be opened.

Check for any debris on these edges (marked in red circles). The picture also shows the proper orientation for insertion. Don’t force it if it binds up—if the parts are dimensionally correct and within normal tolerances, it should slide on easily.

Keep in mind that issues can arise from factors like wet filaments, a misaligned printer, or forgotten compensation settings. It’s always worth double-checking these possibilities.
