The Ultimate Revision of OPENMASK. There have been numerous public citations of our model, but none of them even mentioned our work. IT'S WORTH NOTING THAT WITH OPENMASK WE'RE COMMITTED TO RESEARCHING MATERIALS AND NOT MODELS TO BE SPONSORED. Smilemask is usable with TNT filters, in addition to being compatible with standard respirator filter masks (useful for Healthcare Professionals). OPENMASK is an independent study group dedicated to creating and freely disseminating 3D models of protective face masks against pathogens. Our goal is to find, test, and recommend commercially available materials useful for the creation of protective face masks. Our work is driven by the sudden shortage of these masks on the market. Support our experimentation with a contribution, thank you https://www.patreon.com/openmask In full emergency covid-19, the scarcity of the mask has increased, making it increasingly difficult to find one. This is a valid alternative to the masks on sale. For the larger filter use 8 layers of TNT, for the small one use 2 layers of gauze or cotton wool. Change the filters every day and disinfect everything with ethyl or isopropyl alcohol. The valve disk is printed in tpu (100% infill with ironing of the layers). N.b: There is currently no empirical evidence on correct functioning, having said that we abstain from all responsibilities. Furthermore, it must be remembered that it cannot be used for more than 30 minutes and always remember to respect the distances specified in the ministerial decree.
