Fully Mechanical Traffic Light

First I would to say I love 3d-printy's designs and they are always fun to print and his clips are just great.
This time I modified his Mechanical Traffic Light design to be truly mechanical...
...just to make it more save for smaller kids its always good to not use any batteries/electronics.
So here we go....
I designed aFull_Mechanical_Colorscreen which is just bolted to the Full_Mechanical_Shutter remix of the original shutter (just two holes added).
just print the screens in red, yellow and green.. use transparent filament for the lenses or even dont use lenses at all an you can build a fully mechanical traffic light..

All the other files can be found in the original Thing:

PS: I also found some errors in the original Shutter_Top.stl when importing it into 3D Builder, so I just "heald" it by importing an re-saving it to Shutter_Top_heald.stl

...testprint done and came out better than I expected. Without the colored lenses and the shutters printed in black, the contrast is even visibel from a larger distance.
