Remix of this design here: https://www.youmagine.com/designs/printrbot-play-integrated-fan-mounting-frame I edited this to accommodate a better individual fan shroud on the bottom fan which directed airflow better. I also opened up the front more to allow even more visibility for timelapses, general viewing, etc. I added a small hole next to the LED mount for those looking to feed an LED in from the outside of the shroud instead of the inside.The smaller fan shroud I used on my system, which you can see in the image, is this one here: http://www.thingiverse.com/thing:1255573
