Mask pattern

I drew this mask template for my wife at the beginning of the covid to make it easier for her to sew masks for the kids. 
It works without support, but with a bit of support in the middle it will print nicer.
The prusaslicerrer makes it easy to scale the model. This is an adult size. 

Which one is right and which one is left depends on whether you mark the fabric color or the backstitch.
