RepRap Pro Ormerod iamburnys One Peice Replacement Hotend Fan... Free 3D print model

RepRap Pro Ormerod iamburnys One Peice Replacement Hotend Fan Duct/Heatsink Duct

My main goal for this replacement part was to make the air flow from the fan more direct so i could use a slower a much much quieter fan without loosing the air flow across the print, while i was at it i raised the vents slightly to increase clearance and added cable supports and a tie wrap attachment, it is also one piece which replaces both other parts.

I wanted to make it a direct replacement like most of my other parts, however i had to rotate the heat sink 90 degrees so the air flowed down (not sideways) this required drilling an additional 3mm hole in the heat sink, not a huge deal though.

With or Without the mounting point for dc42's alternate IR Sensor
