Horn-And-Bearing Joint Yoke
A C-shaped yoke for a robot arm joint. The top arm bolts to a servo horn (7 mm centre hole plus two 2.4 mm screw slots) and the bottom arm holds a 624 bearing (13 mm OD) press-fit on the same axis, so the servo is supported on both sides instead of hanging off its spline. The 5 mm back plate has four M3 clearance holes on a 16 x 20 mm pattern to mount the next arm link, and the part prints on its side so the joint loads run along the layers, not across them.
