Filter sheet holder

Filter Holder for Coronavirus Mask. Originally Created for Thingiverse. Having acquired a roll of bulk anti-virus filter sheet, I quickly realized that the thin filter was unable to maintain its shape in airflow, deformed, and ceased functioning altogether. This realization prompted me to design an insert that would force it into a shape where a larger area could be utilized effectively. Instructions: * Print two identical parts (they fit together seamlessly when rotated). * Cut a proper width of your filter material. * Position one side of the filter at the edge and secure with your finger. * Using a dull knife, carefully push the filter into the first slot. * Move your finger to the next blade and repeat the process. * Close the holder with the second part. * Insert the entire assembly into your respirator.
