Reply:use wood. create the 3 leg bones and patella. position the femur over the two other bones. conect the two bones on the botom with nails. attach the patella useing nails or screws onto the botom two bones but keep it floating as so it is not toughing any of the bones. then screw in a small hinge beteen the femur and the other bones.
