Have skills and itching to make a difference with the shortages in coronavirus-related supplies? There are lots of individuals, companies, and communities organizing and many other open-source personal protection equipment (PPE) designs available. Investigate the list below to find a way to put your vital CAD-modeling, 3D-printing, nunchuck skills, and other talents to use!

There’s a lot going on (and a lot of projects!), so just remember, DO WHAT YOU DO BEST and you can help no matter if it’s in small ways are big ways. If you have any to add, please let us know in the comments below.

Disclaimer: We’re not making any claims of the effectiveness or safety of any of the work these organizations are doing. Use the info at these links at your own discretion and risk!

PPE Proposals

Engineers Assemble (Ventilator)

You can add to or download from this open-source library of ventilator CAD files. There’s also a section for respirator masks:

➡️ Engineers Assemble

Isinnova (Ventilator)

Here you can download the 3D printing files for connectors you can use to help convert a snorkeling mask into an emergency ventilator mask:

➡️ Easy COVID 19

This hacked snorkel mask is shown on Isinnova's page for COVID19 engineering.

Durable PPE Project 2020 (Mask)

Thanks to John “Johnny Mac” McEleney of Onshape for sharing this with us. The proposal found in this link is for figuring out how to produce more durable, makeshift filtering masks. This idea adapts scuba masks with 3D-printed connectors and filter materials commonly used elsewhere in hospitals:

OpenLung BVM (Ventilator)

Thanks again to Johnny Mac for this also. This design is in progress and the aim is to use an already available “bag valve mask” (used in CPR) to hack a quick, low-resource ventilator:

Stratasys (Face Shield)

Stratasys is heading up a COVID-19 initiative that brings together more than 150 organizations to produce 3D printed face shields. They’ve also provided the face shield design and files available for download.

Prusa Printers (Face Shield)

These guys give warnings about when creating a 3D printed mask design, but face shields are a different story. Prusa Printers is working on finalizing their 3D-printed shield design, now in its 2nd revision and being field-tested. You can learn more about here:

➡️ Prusa Medical Shields

RepRap (O2 Concentrator)

You can view an open-source oxygen concentrator design that MacGyver would be proud of here:

➡️ Open Source Oxygen Concentrator

Here's a schematic for an open-source oxygen concentrator idea you can find at RepRap LTD.

Genesis Plastics (Face Shield)

Genesis Plastics Technologies, based out of Greeley, Colorado, announced they are also producing large quantities of face shields. They whipped up a design on the fly with a 3D-printed component to help in-state medical professionals facing shortages.

Origin (PPE)

At the time of publishing, the PPE designs that Origin is working on were still under development. We’re told they’ll be made open-source once they’re good to go.

HP COVID-19 Prevention Methods

Hewlett-Packard has free, 3D printable design files right now for respirators, face shields, hands-free door openers, and mask adjusters (to make them more comfortable for long periods of wear). You can also submit your own designs to them. Find out more at this link:

➡️ HP COVID-19 Prevention Methods

Remote 3D Printing Presentations

Jason Lopes is an entertainment industry veteran currently working at Carbon. With children at home he sees the need for education on 3D printing. He is offering educators to host remote presentations to share his knowledge and fill the gaps. See his post on LinkedIn then reach out to him for details:
