An updated version of my earlier Ear Saver. Designed for minimizing retractions.

I got a new face mask with a shorter ear loop, so here is the XL version of my Mk2 Ear Saver. Now with an extra tooth.

I've so far printed 0.62mm in PETG and it worked well. PLA isn't quite as tough, so I'd suggest trying the thicker one. Just scale the Z axis for the desired stiffness.
