Vending machine cup holder

This is a holder for plestic cups that you can found in vending machines, in nearly every European country (at least in Italy). It should fit well and you can hold your tea cup without burning your hands :)
It works well even in PLA (the one I'm using, in the pictures, is PLA!), it's softening just a bit when the tea is hot but maintains full power to hold the full cup without problems.
