This is a from-scratch rebuild of the RoboForce figure SOTA. It's about ⅔ the original scale. There's no pneumatic arm action, but I did include the button in the back that uses a ballpoint pen spring and the arms can bend inward using black pipe cleaners. 

I printed this on my Prusa XL to have the main body with light blue and black in a single print, and black segments in the Radar. The eyes and top half of the head can be painted black later, and the chest sticker would cover the rest. The segments in the Radar can also be painted later. All other parts are single-color prints. Glue is only needed for the shoulders, hands, and the spring for the back button. Everything else friction-fits together. 

Parts are oriented for printing and comments on each part indicate if a brim or support is needed. 

Back Button/Trigger:

Cut a ballpoint pen spring down to 10mm in length. Squeeze one end slightly so that it friction presses into the black button piece. Then use a bit of super glue in the top of the body to hold the other end of the spring. Be careful not to glue the button itself to the body!

Arms:

Each arm will be need four of the Arm Segment pieces, one Elbow, one Hand (Hand 01 and Hand 02), and one Shoulder. The Shoulder can be printed as a single piece, or two parts. The single part requires threading a pipe cleaner around and pulling the end out with tweezers. The two parts can use small pieces of filament in the small holes to align them when gluing together later.

The Arm Segments have a slight angle, allowing the arms to bend inward. Thread a black pipe cleaner through/around the shoulder, then add two Arm Segments, one Elbow, two more Arm Segments, and finally loop around the hand segment. Loop the ends of the pipe cleaner around the hand segment twice to hold it, with a little slack to allow the arms to bend later. See the Arm Assembly images for reference. Then glue the hand and shoulder pieces together. If you find you have too much slack, twist the hand or shoulder 1 or 2 times to tighten it up.

Chest Logo:

The Chest Logo.png can be printed onto either paper or a silver inkjet sticker sheet. You'll need to resize the image to 23mm high by 19.2mm wide. I used the free Silhouette Studio software for that. Once printed, cut it out and glue it onto the body. Even if you use sticker paper, I've found adding gluestick to the edges helps it stick better over time. I also sprayed two layers of clear matte spray paint over the sticker to prevent smudging.
