My school visualizer is made of cardboard, it is composed of different parts: - the first one is the body, this a cube of 15 * 15 * 5cm.
- then the second part is the first arm, this part will be on the top of the body.
- the 3rd part is the most important because this one will give you the right to the second arm to move at 180 °, if you need to show an other thing on the other side of the camera.
- the fourth part is the second arm where will come the camera on.
- and the last part is just a rod to substain the both arm togheter.
And on the pictures does not match with the reality, it's just to get a better idea of the prototype, and it's all made of cardboard
