This zelda papercraft is the Death Armos, this paper model is designed by javierini. The Death Armos is an almost invincible variety of Armos found in Majora's Mask.
It floats in the air and attacks by slamming down to the ground in an attempt to crush Link. Tatl will draw Link's attention to the Red Emblem which appears on their chest. When a Light Arrow is shot at this crest, the Death Armos will flip upside-down. While inverted, it will continue to attack but, while doing so in this state, it will take damage. This is the only way in which it may be damaged. If Link wears the Stone Mask, it may leave him alone.
