Method for modeling a CPR Mask Shape

Why share an approach to modeling the SHAPE of a CPR type mask using NURBS?

First, the modeling approach using NURBS is flexible in that anyone using the NURBS approach can create customized complex designs for CPR type masks or other assistive emergency response equipment.

1) This approach could be used to model many different CPR types masks
2) A single 3D printer can manufacture hundreds of masks at practically no cost.
3) The model can be printed at any scale from pediatric sizes to adult sizes
4) Can be used to conveniently model different types of animal rescue masks
