Printing RepWalker Mutation RA04

Changed the hip-joint axis back to it's original Ø 5 mm. Files are still named 4.1

It was a stupid idea because changing the hip-joint axis from 5 mm to 6 mm also required a new tendon with a 6 mm bore - realized that during final assembly. So it would not make the model easier to build that way...
