Lerdge S cooler

I upgraded my Lerdge S board to TMC2208 for better performance and a lot less noise. The stock cooling for the printer was a small 40x40x10 fan that was about 25mm from the board and only pointed in the general direction of the extruder stepper driver. I wanted to keep things cool and make sure that all of the stepper drivers had air flow. The venting side of the design blows directly over the main processor heat sink to makes sure there is constant air flow. The noise with the two 24v blowers is still substantially less than the stock stepper drivers moving the printer around.
