Alberti Cipher Disk | Encryption & Decryption Tool

I've been using this cipher disk to encrypt notes for a D&D campaign, and the rotating wooden disks feel surprisingly sturdy. The mechanism clicks into each letter position cleanly, making it fun to encode messages. It's a neat way to bring a little history into modern puzzles.

The wooden disks fit together nicely, but the letters are a bit too small to read comfortably without a magnifying glass. It works well enough for a basic demo of the concept, though I wish the engraving was deeper.
