A mount and blower-style shroud to attach a 40mm fan onto the x carriage of a Bukobot v2. As far as I know, this will only attach to a single extruder model as it attaches through one of the holes that a dual extruder would normally obstruct. If you have a dual extruder model, then please feel free to adapt this design to work with it and please upload the results for others to use. Update - June 2014: I just realised that the original upload didn't have the fan mounting plate on the shroudFor this build you will require a 40mm fan and 6 M3 fasteners
