Easy and fast to print surgical mask "spacer" that allowes you to breath and talk more easily.
Four different sizes, refer to the size chart picture.
Each model is also adjustable to add or reduce the clearance between the mask and the mouth.
This is for comfort only, designed for people that have to wear a mask all day long. It won't fight the coronavirus. Use it at your own risk!
It can be printed with any type of filament, but I think that PETg is the best for that use ; it can be washable with hot water, and it is contact skin friendly.
It tooks between 10 and 30 minutes to print depending the size
