Ultraman's mask - 7th of July Google's Doodle

Hi, I'm Yvan from MyMiniFactory Academy. This design is part of a project wich consist of designing a Google Doodle related object each day. As the 7th of July's Google Doodle was about the 114th birthday of Eija Tsubarya, well-known Japanese producer, I created an Ultraman's Mask. The superhero Ultraman was created by Tsubarya in 1966 and was also the first japanese live-action serie to be internationally broadcasted.   The STL file is a single piece mask with theoretically no fragile parts.
