This is a 3D model for creating an Animegao Kigurumi mask. You'll need to print the model in parts, assemble it (I used a soldering iron - be sure to use a tip you don't care about - and some spare filament), then finish and paint it. There's many ways to tackle the finishing job, just look for tutorials on finishing 3D printed objects for ideas.
This design can be a "standard" 3/4th enclosure mask, a full enclosure head or, with a little modification, a strap on mask. The enclosure part is intended to be tied on with string, cord or whatever you find fits the job. Also included are some eye graphics, however you will need to measure the eye sockets yourself and scale the graphics in your favorite image/vector editor accordingly.
The model has been sized to what I think is a good starting point, but it'll probably not be ideal for you. Resize as necessary.
I'd suggest printing with ~20% infill to get a nice, lightweight product. If you're planning to use an additive finishing method (resin filler or such), use the biggest layers you can print reliably to get the job done quicker. If you're planning to just sand and paint, you can still do .3mm layers but your hands will prefer you to choose otherwise :)
