About this 3D model

A working key for the handcuffs used by Dutch and German police. Tested, works perfectly. This is a re-do of [Ray's key](http://ke.y.nu), but I've used a real key as reference, so it's now much more accurate. **Be careful** about print quality. Make sure the key is as sturdy as you can make it, because you don't want it breaking off inside a handcuff.
