Swiss Army key organizer

Swiss Army key organizer.

One of the firt things i made with my first 3D printer 9 years ago and daily used since 2017 (never tightened screws or reprinted it). The version in the file is a new version with a slightly longer eyelet, so the keys are further away from the metal ring and don't get in the way while use.

The hardware required:

•  M3 screws (long according to how many keys you put).
•  M3 nuts (the design fit bot normal and lock nut).

I suggest to put a drop of threadlocker anyway to prevent loosening.
