Bellus3D/ROE Face Mask Fitters

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 ROE. 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.


  1. Download the Bellus3D app from the Apple App Store (iPhone 10, 11, iPad Pro only)
  2. Scan your and/or other’s face as instructed via the app prompts.
  3. User clicks “Mask Fitter” on the lower right.

  8. Chose your best email program to email the file you yourself.
  9. Go to your computer and save the .stl’s from your email to your desktop.

Bellus3D Mask Options

Bellus3D offers three types of mask:


ROE highly recommends that you select either the Standard or Premium mask
