Duct with flaps for 120/80mm fan
thingiverse
This is a fan duct with flaps that open when the fan gets going. I created this to block the vent hole in my enclosure when no venting of the heat were needed. This duct keeps the temp high when you want it to be. I connected my fan to a temp controller (w1209) in order to control the fan. I also created an adapter for a 80mm fan because the fan i had (120mm) never created power enougt to lift the flaps. Hope this will help someone! Enjoy!
