Good job, I like the many cutaways to show exactly what's going on inside.
You may be interested in my simulation of Enigma (https://enigma.virtualcolossus.co.uk) which I wrote back in 2021 (pre-AI!). One of several I've done.
Try it on an Android phone to look around it in VR or on PC/Mac for easier use. You can even send messages to other users over the internet using the radio & Morse key.
Yours is amazing work, and certainly a higher degree of fidelity than I was able to achieve with AI assistance. The initial motivation behind this was largely driven by curiosity around the rotor motion (the ratchet and pawl assembly), and then into how the wiring actually works. For my brain, I needed to press the keys a hundred times and watch the current flow before it started making sense.
I'm curious about how you worked out the inner dimensions and part placements so accurately. Thank you for providing this marvelous free resource!
