This is a remix of a really nice dispenser https://cults3d.com/en/3d-model/tool/shooting-target-repair-sticker-dispenser. Kudos to the author of the original thing.

After discussions with several dynamic shooters and some referees, the most important thing was to make it easily accessible without using clips/ Clips were great but they did break off easily and left sharp edges or broke the entire construct. What we thought was great was to add a magnetic hold or a way to fit a piece of rope and a replaceable carabiner that can be attached to the pants. So I remixed it: two holes allow to fit a rope and a hole in the screw fits a 5x10 magnet-pill.
