V-Core part cooling duct

I remixed the excellent V2 part cooling duct from mcabra so that I could mount it on my particular X-carriage solution for the V-Core. My X-carriage plate is mounted upside down compared to the standard way, so I have two wheels at the top and one at the bottom.
This remix lets me use the two screws that hold the hot end mount to the carriage to also mount the part cooling duct.
In the photo, I've printed the part in Colorfabb's amazing PA-CF filament. This means that the part will tolerate up to 120°C in operation and now I can heat my bed up as much as I want without having to worry about melting my part cooler!
I've added a small amount of aluminium tape to the tips of the duct to reflect the heat coming from the hot end's heater block, which is just a few millimetres away.

EDIT: The PA-CF was a nice idea, but it turns out that it's nowhere near as heat resistant as Colorfabb say it is. Even though I was only heating my bed up to 75°C, the two mounting tabs bent under the weig
