Here are all the parts of the pattern for the 3D face mask with filter pocket and wire at bridge in JPG.
All the patterns are drawn to fit the scale of DIN A4 sheet. If you’re US-based or have a paper scale similar to the US, the recommendation is to print at 120% although I find that it works a bit differently for everyone, someone is OK with the European scale, most use 120 and one reader said 140%.
