I designed this fan duct to cool the workpiece from two sides.
As a result, the filament is cooled better during printing and the printed parts become cleaner.
Important: This part must be printed in ABS or comparable temperature-resistant materials.
PLA, PET and more would melt and hang down.
For the assembly you need:
4 x M2 screws 5-8mm length
Update 10.09.2018:
added a new version with 2 extra screws for more stable mounting and to keep the partcooler staight. For this version you need two more screws. (2x M3 25mm lengh).
The two extra screw are placed where the autolevel sensor plate is mounted.

This is the most efficient 360° cooler for Anycubis Kossel here on thinginverse.
Cooler is designed for 360° air flow around the nozzle.
Peak is cca 2 mm under the nozzle which provides amazing cooling results.
After many attemps to improve cooling capabilities of my printer using downloaded models I become desperate.
So I designed my own.
