This is a remix/cover for the great mask that can be found at: https://www.myminifactory.com/object/3d-print-covid-19-mask-darth-vader-star-wars-115443
I designed it at the request of a local EMT. You'll need to go download his original mask base and grid
Printed with the default prusa .20mm quality profile with no supports and a color change at layer 72.
