Beer cup holder

Just a solution for those who are constantly loosing they're reusable cup everywhere or, l like me, who doesn't like to walk around whit an empty cup in they're and xD. You'll only need a ribbon/lanyard and use where you whant. I've printed in PLA and it works wonderful but, I believe, it'll work good in TPU (if you try other materials, even TPU, give me your feedback).This is for 250ml cups, but I'll post for the 400/500ml later.
