Modified Parts Fan Shroud - Max Micron and other Prusa i3

Newer version with wire management integrated available at http://www.thingiverse.com/thing:1803327 Never really liked the stock fan shroud, finding it directed too much air directly at the whole nozzle and heat block, necessitating higher temps for optimal printer performance. Additionally, it was big and obstructed the view of the nozzle while printing. Also noticed many nice, more directed airflow setups, but they all seemed to wrap around and block the nozzle from view. Decided to design a new one that would be tighter up against the carriage and bring the air flow closer to the actual area being printed, but included a small block to prevent any air from directly hitting the nozzle itself. Explored 3 or 4 different designs before landing on this final one, which works really well. The model images actually represent #3, which was tweaked slightly for the final design that I mounted before taking pictures. Note: Check your layers in the slicer and rotate the model on the bed to get the support material to run from front to back over side to side; it's a lot easier to remove from inside this way.
