40mm Long Leg Wade Fanholder
I´ve Modified the 40mm fanholder http://www.thingiverse.com/thing:231912
With a thicker top for more stability and also modified the holes to fit this extruder http://www.thingiverse.com/thing:512338
Also I´ve made the "legs" for outgoing air loonger to go all the way pass the J-head hotend.
