Replicator Ducted Fans Clip-on to (a) cool Print
thingiverse
Push these Fan Ducts in the gap between Extruder Fan and mounting. The Fans will cool your print as well the extruder. Instructions These are improved versions of my earlier Clip-ons and have a bigger mouth and more airflow. You have to reverse the fans by turning them 180 degrees (so they blow in the other direction). I have added some shorter washers to replace the original ones, otherwise the mounting bolts of the fans/extruder aren't long enough. Print them with 2 shells, 100% infill and full support. Of course the support has to be removed.
