Vacuum Forming the Mask
Next step: vacuum forming! Pulled a test mask from .08 HIPS, and viola!
After a few slight modifications to the mold, I formed a new mask from a thinner sheet of .06 HIPS (to help preserve the sharpness of the mouth and nose detail), left this on the mold, and pulled another mask directly over this. Doing so created the base mask (right), and a slightly larger mask (left). The video of this step is found on this page.
This would allow the two masks to fit over one another like this:
