J Head fan duct

**** UPDATED *****
Thickness in the lower part reworkd, printed OK .

I tried to creates something light to cool down the cold part of the head.Walls are 1mm thick.
The square holes are designed to secure the installation with a small zip tie.
This new version should clip by itself on the head if not, a short time under an air dryer should help.
Compared to the photo shown, the duct has been rezised ( 10 mm longer ) to allow the clipping on the head and the lower duct cool down of the melted filament .

Not printed yet, feedback are welcome !!!
Solidworks file attached for further mods . Help yourself ;-)
