A zero-security 3D-printable stand-in for a Burg Wächter ME/2 lock, aka "magic locker"

These kinds of locks are very helpful for integrating a locking mechanism into 3D-printed models and there are already many models available which take advantage of them. I figure a 3D-printable alternative to purchasing the lock would make these models more accessible.

To use, simply insert the lock and twist clockwise to lock, counter-clockwise to unlock. It's designed to stay put and not jiggle loose until unlocked.
