Victorinox Swisstool belt clip

This belt clip is inspired by this model, although I created the CAD model from scratch. Changes to the original: more space for the belt loop, add a closing mechanism that takes a piece of filament to stay secured.

Use a lighter and heat the end of the filaments, then press the soft filament against a metal surface (e.g. your multitool) to squish it down into a flat shape.

Edit 1: Hudson Bear had the good idea to take a hair pin instead of a piece of filament, see his make for an image.

Edit 2: Added a version with a longer clip, since I found the clip in the original design a bit too short in practice.
