Respirator cutter pattern

thingiverse

This is a custom-made plastic tool designed for use with DIY respirators. The tool's shape was tailored to match the specific design of a respirator available on the Sartor.cz website, which unfortunately only offers the content in Czech. To ensure a proper fit, I scaled up the original "S" size pattern by 15% to accommodate my medium/large European head size. For optimal results, it's recommended to use a roller cutter to cut out the fabric directly around the tool's edge. If a roller cutter is not available, the tool can also serve as a template for using a pen or marker with improved grip on the fabric. An additional resource that may prove useful in creating "laces" for respirators is a design available on Thingiverse, specifically item 3880491. Update: I've added a universal size rectangular mask cutting pattern to this project. A detailed guide on how to use this pattern can be found on Daya.cz's news section, although it too is presented in Czech.
