Servo Robot Arm

The picture is of my cnc milled version of the arm. The files posted are conversions of the parts for 3d printing. Sorry, I don't have a pic of the 3d printed arm.

This arm requires 4-40 socket cap screws, 6-32 socket cap screws, 1/4" aluminum rods, Actobotics Lightweight Hub Horns, 1/4" x 3/8" flanged and non-flanged bearings, M5x25 socket cap screw and lock-nut and 25, 1/4" ball bearings.. Hitec 645MG servos were used. I would recommend something with at least that much torque.
