UPDATE 2/25/21 - Update to instructions - found by a maker - You need 2 fan ducts - One for the left side and one for the right. You need to mirror the fan duct to print the second one, so that it is angled/oriented in the other direction.
UPDATE 2/20/21 - per request, I have shorted the height of the fan duct from 23mm to 19mm to accommodate shorter hot ends. The new fan duct name is;

UPDATE 2/16/21 - Remixed a BLTOUCH mount by hav22 - Now installed and working with BLTOUCH (3D Touch actually from Triangle Labs).
I was not happy with the fan shroud for the Voxelab Aquila. The fan shroud is so large, that it makes it near impossible to see what is being printed, and we all know how much fun it is to watch, and how important it is to see a good first layer go down.
Also, the Voxelab Aquila ships with a hotend fan and 1 print cooling fan. Having only 1 print cooling fan means that one side of your prints will suffer from less than optimal cooling.
I designed this fan shroud to use the factory supplied fans (1 hot end cooling fan 40x40x10 and 1 print cooling fan - blower 40x40x10). You must also purchase 1 additional 40x40x10 blower fan.
Another enhancement here is optional, but for me, I really like to have it lit where I am printing so I can see clearly what is happening. I designed this shroud to hold 2 LED lights. The Voxelab Aquila runs on 24V. The LEDs I am using are (194 168 T10) Auto LED lights. They are 12V. Rather than use a buck converter, I decided to use two LEDs and run them in series. Thus they run on 24V. Google voltage divider network if you want to understand the electronics theory.
To hook up the LEDs, I tapped into the power for the hotend as that fan is always on. The print cooling fans are not always on and I want the LEDs to always be on. The LEDs I purchased consume about 60ma each, so the current consumption is not a big concern. LEDs are polarity sensitive, so you must have the positive and ground correct or they will not light.
Wire the LEDs like this - 24V positive to the + on LED1, then from ground on LED1 go to + on LED2, then from ground on LED2 go to the 24V ground
To add the additional print cooling fan, tap into the power on the existing print cooling fan. They must be parallel, NOT series. Fans can not run in series, technically they may, but you will have issues and if one fails you are likely to see a lot of smoke, so don't do it.
