Micro Servo Robot - 3D Printed Version

Found the Micro Servo Robot on letsmakerobots.com. I thought this little thing was awesome but wanted a 3D printable version that would pick up marbles instead. Plus, I only had 10k potentiometers which seem like they would work better with 3D printed parts anyway. Here is the link to the project I derived this from: http://letsmakerobots.com/robot/project/micro-servo-robot.

Update: Added Arduino program with English Comments.

You will need:
4 - SG90 Micro Servos
4 - 10k potentiometers
1 - Arduino Uno with Breadboard shield
Misc wire and some marbles!

Enjoy!!!!!!!
