This allows you to use the "turbo fan" (or any similar 24v blower fan) with the Chinese upgraded x ends and carriage. This active cooling duct is very heavily inspired by the design this is a remix of, and it is a great design! I just needed something that would fit my upgraded parts. I included the solidworks files to save somebody some time if they need to modify it, It was a bit tedious to design, however, the print quality improvement of an active fan makes it totally worth it!
All you have to do is put a hex nut in each of the 4 hex shaped holes, and use 2 m3x25 and 2 m3x10 screws of your choice with the end caps to protect that nice shiny aluminum, and then lightly clamp it to your x carriage.
I think the aluminum parts are very much worth it for the added rigidity, but I would recommend that you get better bearings than what it comes with, because they have a lot of play.
Here are the links to the parts I used, not an affiliate, just trying to share how I improved my printer.

It's good for the designer and the community (that means you)!
