Marbles Color Sorter

Hi, this is an evolution of my previous ball color sorter. The first one was made by cutting 3mm acrylic with my cnc, and it worked very well... then 3D printer arrived....
so I designed this with Fusion 360.
You need:
2x servos (Tower Pro Micro Servo 9G SG90)
1x Arduino Nano
1x TCS3200 Color Sensor Module
some M3 bolts and nuts and some wires
14mm marbles http://amzn.eu/hjyUwWl and some pieces from this game http://amzn.eu/05BSkjX
