Echo-Class Robotic Arm (Costume and Prop)

A replica robotic arm with complete articulation. The arm works as both a prop and a wearable costume piece, or at least, that's the idea. The model contains several rotation points for good range of motion. Inside the arm is a group of rings that can be attached to small loops within the fingers, allowing wearers to manipulate the fingers similarly to that of a normal, biological hand. To work the hand, take a thin but sturdy material, preferably fishing line, and run it through the small rings
