Swiss key holder - long keys

The Swiss Army style keyring with cut outs inspired by Mark Benson's design - remodeled in freecad - fully parametric, so you can change everything, much more convenient for use than openscad.

I have changed the key ring clip also I make it a little bit longer for accomodation of safety keys made by ASSA ABLOY.

This version is intended to be used with m3 nylon locking nuts and m3 Allen key screws.
