MakerGear M2 Blower Duct
thingiverse
For top-notch prints, a blower is the way to go - specifically one with a duct that hones in the air right onto the nozzle. This approach uses a precision-crafted 50mm x 15mm blower to swap out the standard fan blowing on the part, while also including mounting brackets for attaching it securely to the existing fan that blows on the extruder. This ingenious spring thing (http://www.thingiverse.com/thing:687668) makes an outstanding object for putting your new setup through its paces.
