(Optimised) Part Cooling Duct for Longer LK5 Pro

This is a duct for the Longer LK5 Pro which uses vanes to better direct the air from the stock axial part cooling fan, as shown by Alex Kenis (LINK).

However, from my testing, it didn't make any measurable difference. Probably because the fan is simply pushing too little air anyway. I still decided to share it, in case anyone knows how to improve on it.

I initially wanted to include it in my review of the printer, but since it didn't seem to help, I scrapped it.

There are 3 files: The Fusion360 source file, one STL with smaller holes for the M3 bolts to screw right into the plastic and one STL with bigger holes for M3 threaded inserts (I used the Ruthex ones).
