This is a lock designed link your device to a fixed point (A lock).
I have made some changes for CNC frendly fabrication, so it took a while uploading.
I also changed the name to E-Lock, since Kensington will start sideeyeing me.
(Yes, I know what I said. I'll take this down if nobody wants to see it...)
Hmm, interesting! I'd be worried that a little rotation will lodge a piece in the Kensington hole. How well does this design hold up to torque?
Unfortunely, I can't real-world test since I don't have a printer. But FEM tells me that this device does well aganst torque (Aluminum). Pulling/Yanking is good too.
Give it a try, Axiochus! ;) A test plate is provided.
