Printed this face shield version from 3DVerkstan in both, PLA and PETG.  I was able to fit two of these on a 210 x 210 mm build plate with no skirt.  Initial print for two headbands using 0.4mm nozzle were around 3.5 hours.  After changing nozzle to 0.6mm with layer height at .3mm and extrusion width at .8mm, print time decreased to 1 hour 17 min for two headbands - per 3DVerkstans print settings documentation.  Print/Filament settings that works nice and quick for me are below.0.6mm nozzlelayer height: .3mmextrusion width: .8mm0% infill5 perimetersFilamentOVERTURE PETG Black and TransparentFirst layer temp: 250COther layers: 245CBed temp: 90C
