To print as much as possible
we optimized the design for fast printing.

End of the project: by June the availability of commercial PPE had picked up again


The Berlin-Visor is a protective face shield made on a 3D printer. This design has the advantage that the transparent film is clamped, reducing assembly complexity. The visor was supplied to the German Red Cross during the early months of Covid and also tested for emergency use at the Charité Berlin intensive care units.

25 mins to print – comfortable for hours.

Designed to be printed as fast as possible due to its robust design.

Our Design has a wider headband and clamps in the protective shield foil instead of attaching to the foil with buttons.
This allows us to ship the foil directly without any extra steps to create button holes.

We are very proud that this Design has gotten approved for testing by the Charité Hospital Berlin and was field-tested in one of their intensive-care units.
Ear-Savers for medical workers talking to medical workers on the frontlines of the Pandemic we noticed that the back of their ears had chafed from wearing masks for long hours.

My Ear-Savers hook onto the mask strings and take the pressure off the ears. Designed to be printed in huge stacks allowing each machine to produce over 50 pieces per night. Keeping the ears of health-workers safe.
