E3D v6, 3 fans in 1 mount, 40mm cooling fan and 30mm layer fans
thingiverse
I've taken this remix of "E3D V6 fan duct" (https://www.thingiverse.com/thing:2100038) by @rboutrois and modified it to allow mounting a 40mm fan for heatsink cooling. The fan covers were designed by @DMC3d_and_more (https://www.thingiverse.com/thing:1431743). Note: I've just discovered that "E3D V6 fan duct" was actually a remix of "E3D V6 Fan Shroud" by @carlol (https://www.thingiverse.com/thing:1973156), which already included a 40mm cooling fan. The key difference between my design and @carlol's is the shroud length, with mine being more compact but essentially the same overall design.
