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!

My son was SO cute today, he asked me “Dad, are clouds candy?” I told him they were water. Then he asked “Dad, what’s the Earth’s defense system?” and then I remembered I don’t have a son. And he asked again, with his eyes obsidian black. “What is the defense system father?”
