Welcome! This is a new version of a special medical mask for 3D printing. Perhaps this mask will be very convenient to use as the basis for replaceable medical charcoal filters. Everyone knows that ordinary masks need to be changed very often. This is not the best option for saving material. In addition, there is now a shortage of medical masks. Therefore, I propose to use my model of a medical mask, in which you can put spare replaceable blocks of medical tissue or carbon filters.The model consists of two parts - the external and internal parts. If the outer part is printed from hard plastic, such as PLA, and the inner part is made of flexible material, then it becomes possible to fix the carbon filter or gauze inside the mask. At the moment, the dimensions of the model of the medical mask are reduced to medium sizes and can suit almost everyone. However, you can change the size before printing to any suitable for you. Such a medical mask can protect you from infections if you often change the filter or gauze. It is also necessary to saturate these tissues with antiseptic and antiviral drugs. If you follow the rules of hygiene and wear this mask, you can protect yourself and your loved ones and significantly reduce the likelihood of infection. I hope you enjoy this model.
