Mouthpiece Respirator 3M N95

thingiverse

Your lips form a tight seal around the mouthpiece, enabling you to breathe through the filter while plugging your nose or consciously inhaling and exhaling via this route. The washer is crafted from TPU, a durable and versatile material. To achieve precise circles with no infill, add multiple perimeters to the design. If necessary, scale X and Y coordinates by a minimal amount to eliminate gap-fill lines.
