Extended air duct for 3010 blowers (Haldis3D cooler)

thingiverse

This is an extended air duct for the cooler system that, among others, Haldis3D (Aliexpress) has for sale compatible with the V6 and Red Lizard hotends. I accidently bought the V6 fans with the Red Lizard hotend which, if mounted aligned with the airflow from the hotend fan, makes the part cooling fans blow directly on the heater block. To remedy this I designed these which should fit perfectly under the 3010 blowers. If you also are fitting this combo you should cover the bottom gap between the fan duct and the hotend heatsink with a piece of some heat resistand plastic or metal to prevent air miss direction. No supports are needed if you have sufficient part cooling. If not you might consider a few on the exit.
