Surgical Mask Insert

thingiverse

This is a surgical mask insert that creates a little space between your lips and the mask. The insert slides into the folds near the edges of the mask and fits snugly. In order for the insert to work properly, you have to curl it yourself. I found that taking it right off my heated print bed and holding it curled for thirty seconds does a nice job. An alternative is to curl it around something round, like a chapstick or marker.
