Covid 19 Face mask Free 3D print model

This is a 3D printable mask with 3 layers of filtration. For instruction please check the prewiew image. This model includes 3 mesh parts, therefore I have separated those parts as 3 different downloadable files so that the objects are 3D printed separately . And also I have provided 3 different formats for each of these parts, which ever you feel comfortable. This model is made with blender and the scale is set to centimeters. The file does not include the Human head(except the native).

Note: This face mask does not contain an attached string, for that you can use a ribbon.
