Mouth/Nose protection

thingiverse

Most fully printed face masks seem more suitable for cosplay events than everyday protection use. It's still advisable to create custom mouth and nose covers by sewing them, but when that option isn't available, I designed a simple clip system. This clip holds a filter sheet measuring 20cm x 10cm in place. To ensure stability, the last 1.5cm of each side is folded and inserted into the clips. F9 filters used for VAC are employed as filtration material.
