Face Mask Strap Compatible for Horizontal and Vertical Strings

I remixed the original because some masks (for example some 3M masks) have 2 horizontal strings, unlike the surgical ones that are placed vertically. This very basic yet effective modification allows the string or rubber band to follow a path, so it is now compatible for both.

Only thing worth mentioning is the last 2 teeth are kind of fragile, so don't try pulling from there once printed (I might enhance this section with a bit of time). I tried using this to see if those teeth would still hold up when wearing it normally and it seems to do the job quite well.

If you're worried about its resistance PETG is more suitable rather than PLA as it does not snap off immediately, it flexes more.

EDIT 21/04/2020 - I reinforced the last 2 teeth so that it wouldn't break from peeling it off the bed from the edges. It should be pretty much equal for PLA or PETG.
