Simple clip-on mounts for the MakerGear x-carriage to allow a 40mm fan to blow directly on the hot-end (recommended by Rick) and the part. Print it out, zip tie/screw the fan to the clips, and then clip 'em on! I used a Radio Shack 40mm fan because I was impatient. I'd recommend printing either two at a time, printing with a fan on the part, or printing very slow because the tall part of the clip is small and has a hole so it tends to get gooey/smooshed if you try to print without it cooling down enough.
