Customizable Cryptex Puzzle Box (Secret Code Lock)

A fully customizable cryptex-style puzzle box that lets you build a secret-code container for gifts, clues, or escape-room style challenges.

This model is designed for personalization, so you can choose your own letters, code length, and presentation style. It works well as a gift box, proposal puzzle, scavenger hunt clue holder, or desk display.

Print with good dimensional accuracy and clean bridging for the rotating rings. PLA works well for crisp lettering, while PETG can improve durability. Test one ring first if you plan to scale or remix the design.
