I created a profile for printing 12 shields at a time with a 0.6mm nozzle on the printer. I am currently using Amazon Basics PETG and the photos show the results. I am very happy with the results as they took some tuning.
I have been printing the chin brace separately.
The settings are all in the 3mf and are specific to Prusa I3 MK3S.
I have noticed with some other filaments such as MGChemicals, you may have to increase the temp by 5 or 10 degrees. It's a balance between stringing and "corner cuts" where the radius is circumvented. Depending on the filament, adjust the filament print temp by 10 degrees C or so.
