3D model description


This model is in the process of being approved by doctors in Chile. Use it at your own risk, and only as a last resort, if you have no other approved protection. The recommended measures to protect yourself from infection with the COVID-19 coronavirus are as follows:

  • Stay home and avoid contact with others

  • Avoid touching your face with your hands

  • Wash your hands very often

This model has been divided into two models.


The first is a mask that must be thermoformed only with a hair dryer, and then be molded to the person's face, it also has two protective caps to be able to insert different types that are suggested below.

Filter suggestions according to percentage and recommendations given by professionals in the area.

-Yellow kitchen cloths that must be cut into 4 circles to be inserted two and two in each filter.

-TNT bags that must be cut in 4 circles to be inserted two and two in each filter.

-Cotton-wool makeup cleaners (1 per filter)

(link that indicates the materials with percentage to occupy them as filter)

Model 2.

In the filter folder are added two files with valves to direct the air, the filter one can be printed in PLA or filaflex and the filter 2 in filaflex. This design is thought to save in the manufacture of the filter fabrics by only needing to incorporate these in the valve that allows the entry of air, as well as helping to reduce suffocation by accumulation of moisture.

It is recalled that this mask is in the prototype phase, although it has been validated by professionals in medicine, biotechnology, and others, it is hoped that among all the community, this can be a driving force to further improve the others. That's why it is left available to everyone, the files modifiable in autodesk inventor.
