Extruded filament cooler for Huxley-type extruders

thingiverse

The printed filament can be cooled down effectively using this device so that it doesn't create blobs while building objects within 30 seconds per layer. It assists in constructing bridges as well. To assemble it, you will require a 40mm fan (like a chipset cooler), six screws, and about 20 cm of 2-wire ribbon cable or 40 cm normal cable for power extension. Refer to RepRapPros Huxley building manual's "Hot end assembly" chapter for wiring instructions. You can either connect the two cables directly to a power source or a special fan connector if your printer's mainboard supports it. I used an Akasa AK-210 cooler (compatible with Huxley's 19V) and reused its four screws for fixing onto this device. Two of the screws may require shortening using a file. Additionally, two leftover M3 screws from a computer were used. This device doesn't need support structures during printing.
