This is one method for building off a face topology, the illustrated mesh head is a representation. Foam contact surface (shown in orange, inset from blue) is soft, conformable, and does not match the face surfaces exactly. Like a shoe last. The main build surface is the next layer out, the blue surface. Single Span surfaces, offset and rebuilt within a given deviation, with projected and pulled curves to make it a more manageable build. The contact surfaces from inside face-mounted industrially produced objects are organic, but simplified.
