I like to create jointed figures. You can see my creations here: http://www.soniaverdu.es/p/bjd-art-doll.html I want to share this posable robot figurine with you. It features ball joints and some hinge-like joints. An elastic cord is used to secure the limbs and allow for positioning - no screws required! I hope you enjoy."

Here you can see how it moves: https://www.youtube.com/watch?v=bH3-T-4muZQ&feature=youtu.be

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
