UK Face shield remix

This mask is the easiest design I found so far. I've done all i could to make it easy and fast to print.

Changes to model: I removed the bridge in front for singular extrusions. I also leveled the top of the bridge in front for better supports.

For print settings I also used some extremes: high layer height and very wide for wall adhesion. Also some ironing for adhesion and cleaner top surface. A singular zigzag support on top of the ironed surface for easy removal.

.4 nozzle
layer height = .32
line width = .52
4 walls

print speed = 90mms
wall speed = 70mms

zigzag supports at 30%

2 line skirt

zigzag ironing with 10% flow at 70mms

- included cura file
- included gcode for 2 10stacks positioned with settings as above

perhaps slowdown the speed at first try.
