An updated version can be found here: http://www.thingiverse.com/thing:201638. This is a revamped edition of philsson's 40mm fan duct (http://www.thingiverse.com/thing:184055). I have incorporated a 9mm x 16mm opening to enhance cooling airflow for the PEEK body of the J-Head, potentially reducing PLA jamming risk. This modification might also be advantageous when using ABS, though I am currently testing with PLA only.
