VeryMask v2 – This open source mask was designed to fill the current surge in demand for face shield Masks
Key advantages:
Multi use. Can be sterilized in hospitals, via industry standard Ozone sterilization* systems
Very comfortable to be worn, lightweight, flexible, adjustable size
Very simple assembly
Very cheap to fabricate
Very few and simple parts
Mass production or DIY production
No special tools or tooling required:
For mass production, a printing house should be used to cut plastic sheets by the given design.
For home production, a template tool is attached for 3d printer fabrication, which enables very rapid cutting and hole punching.
Several options for fastening the parts of the mask together:
Either laser cutting for plastic fasteners, simple zip ties assembly, or 3d printing technologies are all suitable. (Fastener part is attached in the 3d model files)
*Home 3d printed parts are porous, and as such do not meet the requirements for hospital sterilization systems. Laser cutting or zip ties are suitable for these systems.
