For all intents and purposes, it is a slightly taller fan duct for the A4 SFX with a Noctua L9i heatsink and a Noctua A9x14 fan. My setup uses an ASRock Z270 Fata1ity ITX.
It is 12mm, instead of the provided 10mm design.
It also has slightly taller screw mount holes (9mm), since the provided version has them mounted so low, 25mm fan screws will impinge (there has to be a better descriptor) the fins when fully seated. Specifically, these are the screws for a 25mm fan, provided with my L9i or L9a heatsink.
Let me know if you want the original FreeCAD files. I don't know if they will be of much help, since I didn't label very much in there.
Also, due to a poor estimation, the walls on this print are slightly thinner than the stock fan duct. It didn't make a difference on my Anycubic i3 mega, but I still know very little about 3d printing.
