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.

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:

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:

➡️ Durable PPE Project 2020

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:

CIIRC RP95-3D (Mask)

he CIIRC RP95-3D protective half-mask was developed by a research team at the Czech Institute of Informatics, Robotics and Cybernetics CTU (CIIRC CTU) in Prague in one week. It is a personal protective device – a half-mask – with an exchangeable P3 filter that meets the highest degree of protection.
