After finding the wonderfully thin and transparent acetate paper, i used the heat gun and molded it over my face mask, and this is the result. The first true prototype of the SPECT-R.

I used an ovular section of plaster to put over the mouth, enabling mouth movement and speaking (molding it over the lips would obviously prohibit this). It was imperative that it closely adhered to the nose, so that it would anchor there, and this mask makes headway with that. Finally, i tried out different methods of perforations, allowing for breathing and speaking from the mouth and nostrils. Here i tried slits in the mouth region, but i felt many small holes would better screen the area and keep harmful droplets out.

This is the first prototype i made of my mask, by now dubbed the SPECT-R mask, (explained earlier in this blog), made of plexiglass. This was before i found acetate, and it was rendered obsolete. Shown by the red marks it has little in common with the facial profile i had outlined, and its only redeeming factor was that it was considerably stronger than the current acetate ones.
