Delve FaceShield closed/hard top concept

Idea is to just close the top of the Delve faceshield without having to do a complete 3d printed frame.

This is done by cutting a PET top to the foam, and optionaly adding an extruded-plastic or 3d-printed "T" ridge where the forehead interfaces to the foam/PET-top
