Added robot_better_hands_and_neck.stl that improves the neck supports so that half the neck doesn't fall apart during printing. Only use it for large prints that are at least 200% scale.
The hand is now connected to the arm through a rod that goes all the way through the hand so it's almost impossible for it to fall off now.
Also removed the built-in supports that came with the original model since auto-generated organic/tree supports would probably work better (with ~0.2 mm support contact z distance so that it easily detaches).
When adding the supports, be sure to support most of the front of the face as well as the back of the head since the supports will be the only thing holding the head up for most of the print.
The author remixed this model.
Increased the durability of the connection between the hand and the arm.
