Design
Design wise I have used various techniques for this final project.
First of all I 3d printed a case for the board I milled (FAB-USB2AX) together with a power supply bus, needed to switch on the motors. You can download here the Rhino file and here the stl file
Some wholes where done on the upper part of the case so I could see the light coming from the board, and know if everything was going well.
Here you see it inside the main wood structure
Regarding laser cut I did some pulleys to pull up and down a string, which was attached to the balls I was lifting.
The size was based on the height I wanted to achieve with the object while moving. The lenght of the circle will be the total distance of the object, taking into account that it will just move 300º, so it will be a little bit less (approx 60cm)
The design is based on three pieces, that should be glued together afterwards. Some material was removed from the central part, to make it lighter so it's easier for the motors to move them. You can download the 2D Rhino files from here.
Very "artisan" way to glue all the pieces together, but fancy and with good results at the same time
The design of the pulley actually, is open from above, so the wire can go through it and connect one motor with the other. As the motor is just turning 300º, it's a good system to connect all motors without losing too much wire.

Finally I used Rhino to design the main structure of my kinetic system, and RhinoCam to nest all the drawings and make them readable for the machine to mill the board
You can download the 3d file from here and the 2D+CAM from here
After everything was milled I started mounting all the pieces, first trying with one module and then with all the rest.
As you can see all the motors had its own support where to stand. At the same time this support were perfect to make the string pass through, so it was "guided" and the movement was more precise and linear.
This is the system pretty much all together
Finally I did some support for the Kinect too.
Here you can see a detail of all the wiring and connections between the motors
And here a video with all the pieces together and working
