By now you’ve likely tried a variety of face masks and found that some fit better than others. For those of you with 3D printers, there’s a quick hack that allows you to get any mask to fit with an absolutely perfect, custom seal.
The Bellus3D Mask Fitter frame is a personalized 3D printed plastic frame that is contoured to the specific shape of a person’s face to improve the peripheral seal of surgical, KN95 or other masks. The frame is automatically generated from a 3D face scan using the Bellus3D Face App or Dental Pro app for Apple iPhone X, iPhone 11 or iPad Pro with FaceID capability.

If you’ve got the app but no printer, you can always send the file out to be printed at a facility and shipped to you. You can learn more here.
