Fanduct V2 (2x5015) + interchangeable jets!!

I wanted to experiment with getting air to directly blow on to the filament in a fine, direct manner, and as close as possible.

This design is a follow up on [https://www.thingiverse.com/thing:2919312]
It will probably be tweaked on further but this current setup should still work - it does for me.
The obvious change is that the brackets give more range of alignment and now has swappable jets!

There's optional LEDs (3mm) for that little extra touch.
It can be used to help illuminate,
