This is simple, emotionless face model. 14 cm width (distance between ears) and around 22 cm height (distance between jaw and hairs on forehead) that fits all regular human.

Note that head model covers almost all front head with ears excluded.

Can be either costumized by post-printing or used template for new mask model. Mask in the picture printed in lowest settings to test its size.

This is my first 3D design. I am planing to design various masks after this and publish freely here, also in instagram (you can follow me to support https://www.instagram.com/mask.bearer )
