This is 3D model of EXO-1 Helmet. From video-game Desteny 2. Model is fully ready to 3D print.

Despite the fact that the Exo is a robotic body with a loaded human consciousness, we were able to make the robot's head in the form of a helmet.

The Exos were the brainchildren of Clovis Bray, though the motive for their creation remains a mystery. During the Collapse, the Exos' memories were shattered and nigh-all knowledge of their origins lost as well. In the Dark Age that followed, the Exos helped build the Last City alongside their organic brethren, with many going on to become Guardians.
