I have designed this model for my girlfriend as she placed her bracelet on her arm and tighten it too much, therfor cutting / breaking the clip or the bracelet would result in the void of the ticket.
I decided to cut it either way and create this file for other people that will have this problem aswell.
Notice: This model is trying to replicate the outside of the original music festival as much as it can so this way staff don't say anything, but the inside is in balance, meaning that it will hold your bracelet but if you need to take it down, pull and it will be taken down. I suggest creating a few of those files for each day of the festival.. I don't like going somewhere else than the festival wearing the bracelet.

From the outside is a simple cylinder, exactly like the original clip, with the mentioned dimensions:

When going into wiring mode, you can see there is a conical shape inside, that's what I have used to catch the textile material, it will also have a few other holes besides it that will intentionally BREAK when you pull a bit harder.
In short terms:
This is what it looks like from underneath and above, you can see the form that it has.
