I finally made it: an XOR mechanism that requires exactly one of two keys to be inserted at a time. I call it the 🗝️ #keyguardian.

This is very useful for example to track where important small things go: Want to take the car keys? You have to insert your name tag to unlock it.

My first mechanical project with #SolveSpace and it was great!

@nobodyinperson Interesting! Similar use case to electrical safety lock-out systems
