This is a robotics arm. DOF, degree of freedom is 6. Fully 3d printable. You have to buy servo motors and screws. All parts supplied in single as STEP file, you have to separate them for 3d printing. After 3d printing and assemble all parts you have to programm the arm to control. Here I provided a simple programm control with arduino and variable resistor. I edited the program in Arduino IDE programmer. Connecting diagram and Arduino IDE file attached. If you want you can use your code and driver module. You can find lots of programm and module in google.
