Modified InMoov head

First of all I want to say thanks Gael Langevin who is the creator of the InMoov 3D-printed robot that I'm building.
You can find the original design on his site http://www.inmoov.fr.
This post is the first one in a series of changes that I have made to the head of the robot.
This post shows the parts that have been redesigned to make room for more electronics in the head. The outside is still the same as the original InMoov head. It's only the inside that has changed. Use the original InMoov head parts for everything that isn't in this post.
I use a smaller servo to turn the head than the original one.
The cogwheels have been removed and the jaw has been redesigned so that the jaw servo could be relocated.
The electronics I have in the head now is 2 standard size servos for the head turn and jaw, 3 smaller servos for the eyes,
a Raspberry PI 2 with a PI camera, an Arduino Uno, a USB sound card, an amplifier, a speaker and a USB transmitter for the keyboard a
