Edit 4/28/2017 : When printed at 100% it was a little small for an male adult. Mask will probably fit better at 110%.

This Deathstroke mask was designed off of GANKUTSU-O-TAKU wonderful pepakura model in Fusion 360.

This mask was sized to fit an adult male but but do size accordingly.

Below is the link to GANKUTSU-O-TAKU pepakura file. Check out his other wonderful models.
