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!

video, showing honeycomb storage wall. a hand grabs a USB stick which is attached to a small white box. The USB stick can't be removed from the box. The hand then grabs a name tag labeled 'Bob' from the right, inserts it into a slot on the box, and the USB stick pops out. Now the name tag can't be removed from the box. In reverse, when reinserting the USB stick, the name tag pops out.
