Prusa Face Shield TPU Band was made to fit a larger head but still be adjustable. I have tried the other bands which were either too loose or too tight. This design was "just right" for larger heads while still being adjustable for normal heads. We are printing the Prusa Face Shields for our local community so I wanted to have a 3d printed band solution to help out.
