В данном ролике я кратко пройду по новшествам, заявленным разработчиками Cura, а заодно протестирую её по аналогии с версией 4.3, чтобы узнать, исправили ли ...

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.
