40mm fan duct PCB Smart Effector
thingiverse
The 30mm fan that is commonly used for the PCB Effector from T3P3/Escher3D makes a sound that's far too loud for my liking. Fitting a 40mm fan duct into the narrow space when you also use the parts cooler can be quite challenging. So I designed an angled fan duct that appears to work just fine. edit 171016: I added a version of the design with the fan mount part thinned out by about 2mm. This one hasn't been tested or printed by me, so I don't know if it will actually work. But I don't see any reason why it shouldn't.
