Update 6/27/19: Slimmed down the fan guard area to reduce noise significantly. Update 6/14/18: After repeated accidental finger whacks, I successfully integrated a fan guard, and bumped up the mount thickness by 1.5 mm. This design disperses heat from the heated bed into an enclosed space with impressive results. It's best suited for use when your bed heater packs at least 500+ watts of power. The design also functions as a quick-release bed cooler once printing is complete, making it easier to remove finished parts. It works seamlessly with a 120 mm fan and a roughly 300 mm bed. I used this specific fan from Amazon: https://www.amazon.com/gp/product/B013DGEBO8/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1
