Here are some photographs of the beginning of the tunnel for air, I have not stuck the various parts
together yet the plexi is not pretty because I have not withdrawn yet film them protective in order avoid having knocks inside
I placed at the rear of the tower, a plate of plexi in which I have to still come to cut out the site of food as a site for a fan of 120 mms who goes evacuated air in the tunnel.
