EDIT: After a recent rereading of the manga, I noticed the front piece of the mask has curves on it, so I replicated the curves in a new optional piece for the front!
So I've been working on this for a while now, through numerous iterations and tries, and now I think I'm done. This is Midoriya's mask from My Hero Academia, the 3d printed parts of it anyway.
So a bit of back story, I've been wanting to make my own Midoriya mask, about a year ago I made my first model, but it was fully printed and solid, and didn't fit my face, and then I printed and printed and tried and tried again, always failing, so I gave up....
Till recently, when I had the realization Midoriya's mask isnt a solid piece, its instead plates with flexible parts inbetween, and so I beta tested by getting an old mask prototype and hacking it up with the dremel to duck tape it back together but flexible, and it works, it fits perfectly.
I then redid the whole model, being as anime accurate as possible and getting rid of the non printable pieces.
You will notice the mask is missing the black parts, thats on purpose, they need to be flexible, meaning they will need to be made out of foam, you will also need foam to connect each plate evenly, and then use foam to do the ear cover part, and elastic to make it fit to your face.
I have not printed this new version yet, so any first time tries, please let me know what to improve!
There will have 5 files to print, with 4 of them being repeats that you will need to mirror, the files are to scale of my face, if you have a smaller face you will need to adjust for that.
