Replacement Key Handle for Security Doors

Unfortunately, the handle of my security door key broke, so I decided to rebuild it as closely as possible to the original, as the rough key was really too awkward to use.

The measurements were taken from a Securemme K2 key for European cylinders, but it seems identical to other keys from other brands (also for security doors with European cylinders).

I printed the model in PETG vertically with a slight brim to increase its strength and prevent it from weakening, for example, if left in the car. If you don't have any particular problems, you can also print it in PLA or other materials (also because it is very fast).

If printed vertically, it needs light supports at the base, otherwise it can also be printed horizontally (even if the layer arrangement is not the best).
