I'm going to put this here, right at the top:
YOU CANNOT SELL THIS MASK IN ANY SHAPE OR FORM, READ THE CREATIVE COMMONS, STOP TRYING TO SELL IT ON ETSY OR ANYWHERE ELSE.

UPDATE: So I did a new update for the mask, but I've chosen not to release it for free since I honestly need some of the support at the moment, the new update is basically a full mask revamp on Etsy with a much more narrow look closer to the manga. I'll of course keep these files up for free since I released them for free, but if you want the newer closer to the manga version, heres where its availble, only for about $5 USD (conversion rate is weird) https://etsy.me/3myKbBQ I can honestly use all the support, especially if you like what I do here.

EDIT: New edit already! The latest issue of the manga (Chapter 310) showed better shots of the mask from the side, meaning the ear piece needed to be changed, but im still keeping the previous ear piece up incase people prefer it.

My new and improved Izuku Midoriya Mask! With heavy reference from the latest manga chapters, and this time with me actually using a proper human head (my head) as reference to make sure it actually fit properly, here it is!

Mask should fit a normal grown male adult, make sure to scale it right to fit your own face. I left room for foam in the ear hole areas and around the face.

I haven't printed it yet, so any quality of life improvements please leave them in the comments!

Happy printing!
