"I'm really into mechanical calculators and also security. A mechanical cipher machine would be really cool to add to the collection." Then I saw the going rates for vintage WWII cipher machines...

@ajmartinez That would be an incredibly fun project. Most of the replica kits I see out there just replicate the outside, the inside is an arduino or similar. I'd love to replicate a mechanical version.

Apparently there are CAD renders here: grabcad.com/library/enigma-mac!

@ajmartinez There is also this, but the original site is offline now so we'd have to rely on wayback machine: thingiverse.com/thing:1813308

@kyle fortunately we’ve been on the web since it was but a wee series of tubes. I’m sure we can find whatever exists as prior art, and I also think it would be super fun to make a mechanical cipher machine even if it has to be designed first.

@kyle
I have really enjoyed the mechanical calculators that you have been posting also.

@jlcrawf There's more to come! I'm going to feature a new one weekly, spaced out so as not to deluge my timeline all at once.
