The Mask Fitter holds the surgical or procedural mask snugly to the user’s face. This is accomplished by scanning the face with Bellus3D’s Face Scanner App, allowing the app to automatically design a custom Fitter .stl file to allow the user to send file to Master Labs. The Fitter is placed over the existing user’s mask, held fast with rubber bands or similar, and helps prevent any gaps around the edges of the mask.
