Decided to upload some pepakura files I've made. Feel free to use them or modify them. Doesn't include the visors because I don't believe them necessary to fold. If there are any problems with the files, let me know.
Edit: I scaled them up because if they are too big you can fix that with padding, them being too small would be a bigger issue.
