Bed Cooler and Chamber Heater

thingiverse

Update 6/27/19: Thinned the fan guard region to cut down on noise. Update 6/14/18: I wacked my fingers enough times to add in a fan guard, I also increased the thickness of the mount by 1.5 mm. This was created to re-distribute heat from the heated bed to an enclosed chamber and works quite well. I would suggest only using it for that purpose if your bed heater is 500+ W. It also serves as a bed cooler once the print has completed so that parts will pop off nice and quickly after they're done printing. This works with a 120 mm fan and a ~300 mm bed, I used this one from amazon: https://www.amazon.com/gp/product/B013DGEBO8/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1
