A Mask For All

An issue of great magnitude surfaced: the global shortage of N95 masks, procedure masks, and PPE, which are desperately needed by caregivers on the frontlines of COVID-19.

Like many concerned citizens, we wanted to help flatten the curve and stop the spread, so we created A Mask For All.

Developed by a team of experts to be easily 3D printable, this face mask was created to provide quick and easy access to anyone with a 3D printer and their communities. This mask is reusable and contains a filter insert for many different types of easily available filter media can be used and disposed.

This design requires no support structures.

PRINTING INSTRUCTIONS (READ BEFORE PRINTING!):

Everyone’s face has slightly different proportions. This model was created to match a face with 124mm (4-7/8 inches) between the crest of their nose and the bottom of their chin. In order to print a mask that properly fits your face, you’ll need to measure the distance indicated in the attached images and scale your model accordingly. Use a tape measure or calipers and measure between the two indicated points. If you’re using a tape measure, hold one end to the tape measure to the crest of your nose. Place your thumb on the tape measure where it contacts the bottom of your chin. Then, you can move the tape measure away from your face and see the distance indicated by your thumb’s position on the tape measure. To find the proper scaling value, divide this number by 124mm or 7-7/8 inches (4.875 inches). For example, if you measured the distance to be 110 mm (4.33 inches), your scaling value would be 110mm / 124mm = 0.89 (4.33in / 4.875in = 0.89). This scaling value applies ONLY TO THE Y-AXIS, which is the long axis of the mask. DO NOT APPLY THIS SCALING UNIFORMLY TO ALL AXES. This would make the mask too small and too tight around your nose and cheeks. This scaling value does not need to be applied to the filter insert.
