Show HN: A working 3D model of an Enigma machine
A developer posted a functional 3D model of the Enigma cipher machine on Hacker News. The Enigma machine was used by German forces during WWII. The model includes rotating rotors, a plugboard, and a reflector, allowing users to print parts and assemble them to observe the encryption process. The project shows how 3D printing can revive historical tech, and the author invites community testing and suggestions. It also includes a guide for assembly and wiring.
