A simple but very effective cable tie with a length that should work for the most common USB cables.

The first few times it will be a pretty tight fit, but since it wears out a little bit after some usage I decided to keep it like that.

In my tests I've used Sunlu TPU which prints great from my experience.

Just please remember that Bambu doesn't recommend printing TPU on the textured plate. I've used the Engineering one with great success.
