Fan

N.B. The dimension of certain part have to be scaled of a factor x100!

The .stl files are complete but there are some defects which I
discovered while mounting the fan:
- the pins do not enter in the small corresponding holes (I
used some tolerance while drawing the parts but it was not
enough);
- the hole for the plug is not in the drawing, I used a drill
to create it;
- the eletric motor is a common 9V motor, in the base there is
also space for a 9V rectangular battery;
