Coxa - hip joint (surface melt version)

thingiverse

For walking robots, utilize the hip joint designed for metal geared servos. Additional leg parts can be found in ancestor things: http://www.thingiverse.com/thing:53120 and http://www.thingiverse.com/thing:51425. The part's weight-bearing capacity is currently unknown; if the printed part appears bent, use the optional lower clamp part. Compare dimensions with tmbg's "3DOF Mini Quadruped" for an optional experimental clamp version. Adjust OpenSCAD parameters and print the part with at least 3 perimeters for optimal performance.

Create a small hole in the gear trap, heat the inner surface using an alcohol torch, then press a metal geared servo into place. Secure with a screw, ensuring no gap between the printed part and servo body. This method is not suitable for nylon geared servos; resin may be a better alternative. Attach the leg to the printed coxa part, securing it with another screw. An experimental version shows the coxa part alongside an optional clamp part, but this may not be necessary. The provided STL file is for 27.5mm high servos.
