Cocoon Create Airflow Focus

UPDATED TO A BETTER DESIGN:

I am very new to 3D printing, having received one from my fantastic daughters for Christmas (from Aldi) and I have had the usual trials and tribulations getting good prints.
I read that most people add fans and printed fan ducts to cool the nozzle, not wanting to delve into that so soon, I looked at how I could focus the air flow I have from the integrated fan on my printer and have come up with this model, it seems to work well and would love someone to download, print and test it to see what they think.
(of course there is the remote possibility it does nothing at all)

Note: The part in the pictures was printed on the fastest print mode I have so it looks a bit rough but still serviceable
