Ender 3 Cooling Ring

I've had a great deal of success with ring style fan ducts on my DIY printers in the past so I thought I'd look for one for my Ender 3, I could only find one so I decided to create a new, sleeker version.
The one I found was created by https://www.thingiverse.com/Filboyt
His version is really good, and I used his mounting method which is why I'm mentioning it.
But to be clear, this Thing is not a remix, it is 100% designed from scratch!

Printing with the stock Ender 3 fan duct should be "good enough" but I recommend reprinting with this ring duct installed, you should get a better print especially on the inside.

This is designed for the newer Ender 3, if anyone would like it modified for a different Ender and can provide dimensions please let me know and I'll create a variation.

It mounts using the 2 lower screws that the stock duct uses (see pic 2)
Your nozzle should stick out just below the bottom of the Ring Duct (see pic 3)
