DISCLAIMER: All devices on this page are no certified medical devices. According to current regulations it is not allowed to use them on humans. None of the individual contributors and sponsors nor anyone else connected to the project can take any responsibility for the results or consequences of any attempt to use or adopt any of the information presented on this web site.

NOTE: This is a research project (see FAQ). At this point it is not recommended to print any parts and use 3D printing resources for other things (see FAQ). The project is in progress and undergoing rapid changes! Since research is ongoing and no reliable status has been achieved so far, we currently do not publish any CAD/STL files or software source code. Nevertheless, as soon as a device meets the necessary requirements, it will be made open-source.


The objective is the development of a simplified ventilation device that is built with the help of a 3D printer and a few components so that it can be easily reproduced and assembled by volunteers all over the world.

Design Strategy

Strict application of the KISS principle. The devices operate standard bag valve masks. Overall design goal is to minimize complexity as well as the need for additional non-printable parts, specifically considering electronics.

Here you can find an overview of the designs that have been developed so far.

See the designs prototypes in action on Youtube. More details on the designs you can find here.
