This fan duct directs air flow from 2 fans 25x25 onto printing part and uses one fan 30x30 to keep heatsink cool.
Design goals:
Compatible with E3D and some clones (with same dimensions)
Compatible with direct-probe effectors like Buffalo effector http://www.thingiverse.com/thing:1093345 and Snow effector http://www.thingiverse.com/thing:868258
Minimal footprint - all fans are kept in effector dimensions
Lightweight - thin walls, no infill at all, weight 8g (PLA)
Reuse 30x30 default fan from E3D
BOM:
2x 25x25 12V 1.6W (130mA) fans.
9x screws M2.5x14 (for 25x25 fans, one for mount on extruder)
4x screws M3x14 (for 30x30 fan)
1x nut M2.5
1x washer M2.5 or M3
Fan duct mounted on effector with single screw - you'll need to dril a hole for it or print a new holder part with a hole.
There are two STL models provided, with support and without it. I have printed the one without support, but with light overhangs.
UPD: Added E3D Volcano shroud.
UPD: I made one shroud for Volcano and electroplated it with copper for better thermal strength :)
