Redirect Power supply air blow - For Delta Printers

This project was created for personal project. My Kossel has a 30a 12v power supply and was placed in my kossel on the top.

The air goes to the printed area and when i'm using ABS filament, the wrap is very high.

This piece help me to send the air to top of printer.

Someone send me a mail talking about a problem with some slicer softwares and this file.Software as Simplify3D for example... Now, the new file (v4) will make a unique piece on slice.

Thanks
