HIC Prusa i3 Fan Duct with Heat Break Cooling
thingiverse
The Fits HIC Prusa i3 is my printer of choice. Issues with a heat break that got too hot kept me on my toes. My solution might just be the ticket if you're dealing with similar problems. I made the crucial adjustment by printing with the back plate flat against the bed and having the ducts pointing upwards. Using supports worked for me, although it's probably not essential to include them. UPDATE: http://www.thingiverse.com/thing:1306170
