This is the Exo-Suit from my favorite movie when I was a kid. It's for doing battle with the things that mostly come at night... mostly. The model is fully articulated including the arms, legs, grippers and cage.
Everything is 3D Printed except the pins for the cylinders are cut paperclips and the "hydraulic lines" are made from flexible filament. I recommend regular resolution with 30-50% infill. The print in the pictures is PLA. Some parts require support material. I highly recommend a test fit assembly before applying any glue. I use superglue. Be sure to keep the glue away from the gripper slides, pivot pins and flexible joints.
