This fan duct suits my replacement carriages, mk5 extruder and a E3D hot end. Due to the bulk of the E3D hot end, there is no room for a traditional front mount fan duct. Due to the added length, however, room is available under the the extruder carriage to mount a 30 x 5 mm fan.
This can only be used my my replacement Solidoodle carriages, specifically the updated v2 version. If you already have a previous version fitted, the only part that is a must for this is the centre_front piece.
Print fan duct as is, no support needed.
Fan attaches to duct with 2 x M3 x 10mm screws.
Duct attaches underneath carriage with 2 x M3 x 25mm screws. Nut traps are built into the centre_front piece of the carriage if you would like to secure it very tightly.
