Narrow profile layer fan for the Rostock Maxv2. After adding an enclosure (http://repables.com/r/447/) the fan(s) would hit when printing very large objects that filled, or almost filled the bed.
This design may not have as smooth of airflow (although I've seen no drop in performance) it does pull the fan in almost 2cm tighter to the head so they clear the enclosure when printing large objects.
