I got tired of looking to buy fans for the upper cooling compartment. I managed to make a few after some trial and error so the last one I took some pictures of the process.
It took about 20 minutes to make the four after they're trimmed and under the cover screen I believe they'll look fine.

This is my goal, a shot of the cooling compartment of a real Warhound.
This is the empty space to fill.
I started by making a box to house the fans and AC units. The fans were mde up of small triangles of 0.25mm styrene. The completed fans are 9.0mm in diameter.
