At work, I came across an unusual situation. This lock had minimal resistance to turning, but it used a square key, like the kind you might use to wind a clock. Since it didn't take much pressure to turn, I figured I could print a functional key, and the basic shapes should make it a basic model. Of course, these locks came with keys, but they were out of the way, and who wouldn't want to jump at the opportunity to have a unique and usable key?
I had a cheap plastic (no, suuuuuper cheap) caliper in my desk, but that was all the precision I needed for this, so I jotted down the radius of the circle, the width of the square, and the depth of the socket.
The blade was easy enough to model, and I used a half-cylinder as the bow because it should print reliably.
The printed version was strong enough to turn the latch! I glued some magnets to the bottom so it would be easy to find. I am happy I made this because it was a fun little distraction.
