RobotArm by FrN

Here is my re-mix on the F.Tobler robot arms. Most of the files are the same that that from Tobler. I only attached the new parts here. Below are the changes that I made:-
1. Better wiring on hiding the motor cable.
2. Fit the mini-stepper motor board inside the lower shank.
3. Change the endstop plate to endstop with home switches.
4. 2 home switches added as shown for upper & lower shank.
5. Add cables outlet under the new endstop module.
6. A new RAMPS case made with 5cm PC Fan.
7. Tie gripper motor input from 5V to 12V to improve response. (new)
8. Modify the gripper fingers for holding pen and marble. (new)
