After 50 hours I got this beauty before starting production of masks https://ift.tt/2UM3Z77 https://ift.tt/3bTk4xu
Mask fitting game changer! Placing roughly 1” of the mask into warm water (not boiling) for 15-30 seconds makes the outer rim playable to form to your face. I add a silicone bead to the rim for added seal and am getting a perfect seal so far on me and my wife’s face. https://ift.tt/2RavQf1 https://ift.tt/348LexI
Pack and Stack. Printing shield frames on a 300×300 bed, you can fit 3 on the plate. Stack with gap equal to 1 layer between. I did 24 overnight and pulled apart by hand. https://ift.tt/39HK3GK https://ift.tt/2UJlDbC
