***READ ME*** There are a total of 5 sizes for a universal style of a cloth mask mount that are modeled within these files. 1. Extra Small (80mm x 100mm) 2. Small (85mm x 105mm) 3. Medium (95mm x 115mm) 4. Large (100mm x 120mm) 5. Extra Large (110mm x 130mm) These sizes are predominately determined upon the measurement from the bottom of the nose to bottom of the chin. A measurement of the horizontal distance from the outermost edge of each eye is also provided. These models have been saved in 3 different methods to ensure everyone can access and view them. a) Solidworks models, designed in SolidWorks 2019, if you have SolidWorks b) STEP file, if you have an alternative CAD program c) 3D PDF, if you do not have a CAD program There are 3D printing models for each of the components. A model for injection molding was not created. This effort was funded by the DOE Office of Science through the National Virtual Biotechnology Laboratory, a consortium of DOE national laboratories focused on response to COVID-19, with funding provided by the Coronavirus CARES Act.
