3D printable eye mechanics with the following features:
Each eye can be moved individually independent from the other.
Eye lids can be opened and closed independent from the other.
Eye mecanichs need five cheap SG90 Servos.
To get open source software running on a Rasperrry Pi that can drive the servos in a puppet, visit http://bechele.de/pages/english/73-0.html
Some parts are needed twice or four times, so please have a look at the images, there you find a reference which parts are needed how often.

15.04.2018 - Updated servo base to allow to mount the left eye lid servo on the inner side of the mounting studs. This is required if you want to use adapt the mouth thing to the eye mechanics.
Additional explosion images added for better understanding the mounting of the thing.
