I recommend printing oh highest quality for good fitment. No need material support should be needed.
Video on assembling the robot figurine with elastic cord: https://www.youtube.com/watch?v=-oG39NoSJGM&feature=youtu.be"
The elastic cord that best fits the robot is 3mm in diameter. In the video I use elastic cord 3mm diameter in neck/head and arms and legs thinner one, but the robot works best if you place one of 3mm in diameter and quite tight knots
Layer height(mm): 0.1
botton/top, Shell thickness(mm): 1.2 It is important for delicate parts of the neck, arms and hands
Fill density%: 20
Print speed(mm/s): 40
Support : none , but if you have trouble, you can choose "platform adhesion "
I've printed pla 210º (c)
Note: Be careful with the joint at the base of the neck and fingers, they often remain stuck in printing, and is difficult to get moving the joint
