I first printed it out of PETG, but it was very stiff, so I got some TPU 95A HF from Bambulab, and that works perfectly.
I would even say it fits better.
I recommend printing it like this (picture above) because it's easier to get the support off your lips.I don't recommend printing it like this because it makes the support really difficult to remove (see image above).
