Currently I am using an E3dv6 Lite hotend on my delta style 3d printer. Bowden design, as almost any other delta printer is. And was wanting to re-print a new fan duct for my printer, but I was thinking about adding a second, or third if needed. Does anyone have any great fan duct design’s that they would like to share? And would two fans be good enough or is three overkill? http://ift.tt/1TNZT7A
