Kardatoran Arm Set

That was a long time I wanted to finish this little project of create a proper elbow on Av-Matoran arm. I splitted it in two parts wich can connect and move like a regular bionicle articulation (pneumatic rigid 3mm hose needed to maintain the elbow, though).
I printed up a prototype and worked well, so I decided to put it on Shapeways here

Hope you like it guys !
