Dazzling 3-color whistle

This thing was made with Tinkercad. Edit it online https://www.tinkercad.com/things/31UpAohzQ47

i got the original(?) from http://shop.prusa3d.com/forum/download/file.php?id=3426&sid=70fd91101ad6b785cc645f17733c1a4a
in a few months i'll have my original prusa i3 MK2 3D printer (waiting time for delivery is about 3 months... :-( ) and then I will be able to give this a try... I hope i can make complex multicolor 3D prints like this wit it...
