J-Head Bowden Extruder with Fans

J-head Bowden extruder, with a socket hole for 1/4" BSP push fitting. Mounting holes are 30mm apart and the part is designed to be mounted against a vertical x-axis. There are screw holes for two 40mm fans angled down at the extruder tip, or one front mounted 40mm fan blowing across the PEEK.
This really is a work in progress - I can't decide whether some bad prints are from bad fan positioning or my printer not being set up right for my new filament. Please let me know your experiences.
