This papercraft is the Sabre Turret, the ability unique to the Commando Axton in the video game Borderlands 2, the papercraft is created by Raiziel. The size of finished model is about 500 (H) x 498 (W) x 349 (D) mm.
It is both the name of the skill, and the turret deployed by the skill, an automated weapons platform that can distinguish friend from foe and dominate a small area of any battlefield.
The Sabre Turret's initial form is modest, but Axton's skills can change the turret's basic model to fill a variety of roles. It can be equipped with ammunition belts, rocket pods, a targeting laser, an extra gun, a shield emitter, and mag-lock bases. Other skills (a "nuke" explosion when deployed, longbow technology (increased durability and deployed like a Longbow grenade instead of a Lobbed grenade), and the ability to deploy two turrets simultaneously) improve the turret's offensive and tactical use, but don't actually change the turret's appearance.
