BLM COVID-19 mask

This mask filter is designed for use with the provided stencil, which can be found at https://www.thingiverse.com/thing:4438558/files. I enhanced and modified this design by connecting the bottom of the wrist to create a stronger structure. This stencil fits most standard face pads. For optimal results, I suggest laminating the filter using two layers with a non-woven polypropylene sheet from a reusable shopping bag to achieve a high-quality filtration system.
