fully posable robot

#####If you print this robot, i would love to see your makes or hear about how the printing process went for you! That will help me to improve my designs. Thanks!

#####CONTEXT
I wanted to print a posable figure but the models I found either broke during assembly or were becoming too loose after a few days. This is my attempt to design PLA joints that are easy to assemble but not too loose.
I designed 3 joints: a x axis joint, a z axis joint, and a ball joint.
My solution is to split the joints in 2 parts: a cylinder in the xy plane, and a part that tight fits inside. This way the joint does not break during assembly, but can be tight afterwards.
It tooks many many trial to find the good compromise (see last photo with all the scraps).
And because why not, i made a posable robot (terminator T9 style) using these joints. It can be printed in 2 colors for more visual impact.
