N95, 3d printed, Replacemnt Straps

Healthcare professionals all over the country are facing shortages in personal protective equipment (PPE). Currently, the use of N95 masks far outpaces the availability and manufacture output. Supply chains, at best, can promise an increased supply in weeks, but the essential need is right now. As a last resort, medical professionals are forced to reuse the masks they have on hand. To reduce the risks of reusing these masks as much as possible, N95s go through a sterilization process that makes them safer to use, but may also cause the mask's straps to fail.

To resolve this problem, Sarah Flora of Geisinger Health System has designed a temporary solution—3D printed clips and straps.
