A fan shroud for the 1404/2.4 version of the Printrbot Plus with dual extruders ONLY. Replaces the wooden shroud that comes with the printer, which was catching on prints for me.This is a work in-progress, and I am currently having an issue where it prints with holes in the sides. Still works pretty well.Based on this fan shroud by nickroosen:http://www.thingiverse.com/thing:339763Which is for the same printer, but the single extruder model. All I did was stick two of his design together and bridge the gap, and add tabs for the holes in the wood.
