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;
• the front cover grid has some clips to fix it to the cover grid, but they are not dimensioned correctly.

I had no time to re-design and re-print the components, maybe in the future. For this reason I provide also the original CAD file, I used inventor: feel free to re-design or improve the parts! thank-you, bye :)
