I am the CEO of MatterHackers. We have been coordinating efforts in response to the Covid-19 medical PPE shortages, and are working closely with healthcare professionals that have already approved the models that I've uploaded. We have had over 1000 makers and maker labs sign up to assist and have had dozens of hospitals and medical professionals contact us to receive assistance. You can see some of what we have set up here. https://www.matterhackers.com/covid-19. We are hopping to submit some more designs to ensure that many options are being evaluated as to their efficacy.
