Coxa - hip joint (surface melt version)

This hip joint for walking robots can be used for metal geared servos. The other printed leg parts of the pictures can be found in the ancestor things:

At the moment I don't know how much weight this part can carry. If you see the printed part bending, then you can use the optional lower clamp part.
I added a picture including the coxa part from tmbg's "3DOF Mini Quadruped" to compare the dimensions of my optional, experimental clamp version.
