covid mask modular ear saver

hello, for those who are looking for a modular ''ear saver'' for FFP2 mask, this is my design.
For better fit, I recommend to print it in TPU.
but you can print it in -antibacterial-PLA (red items) and give the curve it in hot water.
all items are printed separately.
the square ''ring'' must be printed in TPU as it have to tightly fit the ear saver branch.
