nobodyinperson, 4 months ago 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! EDIT: Now on #Printables: https://www.printables.com/model/793767-keyguardian-dual-key-xor-mechanism #3dPrinting #CAD #3dDesign #Screwiverse #HSW 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.

foone, 4 months ago @nobodyinperson you fool! If you make a physical XOR mechanism, that's dangerously close to making a logic gate. What if someone prints 12 million of these and builds adders and ALUs and memory and now it's running doom!
