Servo Robot Arm
thingiverse
The photo is of my CNC-milled version of the arm. The files shared are conversions of the parts for 3D printing. Unfortunately, I don't have a picture of the 3D-printed arm. This arm requires four 4-40 socket cap screws, six 6-32 socket cap screws, one-quarter-inch aluminum rods, Actobotics Lightweight Hub Horns, one-quarter by three-eighths flanged and non-flanged bearings, an M5x25 socket cap screw and lock-nut, and twenty-five 1/4 inch ball bearings. I used Hitec 645MG servos, which I recommend as they provide a significant amount of torque.
