Video via smartphone

If you have a beard, shave it off. Stand in a well lit room and tilt your head slightly upwards (and keep still). Let someone else make a 180° video of your face in full HD (30fps - 60fps). 
Attention: It is not possible to move the camera by yourself. This would cause the 3d image calculation to fail.


Calculate 3D image

Upload the video to our customisation website. We will calculate the 3d image of youre face and inform you after completion by mail. Don't worry, your data is very well secured and will not be given to third parties. 


Customisation mask

With our script we customise the mask directly onto your face. When this process is finished, you will be informed by mail. Afterwards you can download your individual mask. We would also be happy if you donate some to support our development.

*: Our open source publicated masks are not the final versions. There may be extensions / changes due to subsequent improvements. Our masks are currently not medically certified. We cannot assume any liability for the quality of the printed objects. So far there are only studies that suggest protection of others but not the wearer of the mask. The masks only protects if a filter material is inserted. How well the mask protects depends on the filter material and the fit. Please do not forget the other hygiene measures, this mask does not replace them.
