Face shield mask model 3 for smaller 3D printers

Originally published here on Thingiverse. This is a modification of a mask I was working on with a team of my university, with the purpose of providing technically studied, tested and redesigned 3D printed supplies, to medical centers here in Argentina in this global health emergency. I modified this mask for smaller printers than the usual 20cm x 20cm hot bed. The smaller side of the hot bed must be 13cm or higher; and the other side must be 18.5cm or higher. With the feedback of medical profesional from the original model and this second model, we create a new version with the some improvements: The contact with the front head is now curved, reducing the contact area, and making easier to print than the previous ones. The attach for the acetate plaque is now semi-foldable, that makes it easier to print and assembly. This model can be used with a 30cm wide acetate. To cut the corners of the acetate plaque I've designed this stencil.Warning: although the original model was designed and approved for use within medical facilities in exposure to COVID-19 patients, the model posted here was never tested for this use, so it could be used for public attention but it must not be used as first barrier against these patients.
