Not really satisfied with the available stepper coolers I decided to create another one with focus on air flow and user friendy mounting.

The cooler is not covering the whole stepper area including the sockets, it is only covering the upper surface part creating an air tunnel that exchanges the air to the heatsinks.

The parts are made very thin, so that it will not put any pressure on the surrounding equipment, escpecially the stepper motor wiring sockets and the cacacitors nearby to the stepper driver sockets.

The outlet of the cooling air is not directly attached to the casing, this makes the assembling a little bit easier and parts of the air stream is reflected back to keep a small but constant air flow over the Trigorilla board.
