The aim is to gently widen the inside of the vent cover to slightly increase the air flow rate.

In my case, I printed the vent covers in orange.This is to make it easier to visually tell whether the vent is open or closed. In the process, I decided to make some slight changes to the original design to improve not only the appearance but also the functionality, which is how I came up with this piece.
The difference from the original design is subtle; I just rounded the edges of one side of the hole.
I haven't tested whether this actually improves breathability.
When assembling, make sure the rounded side is facing inward.Otherwise, the airtightness when the vent is closed will be compromised.
I recommend using ABS or ASA for printing, as PLA will not be able to withstand the heat. The dimensions are 0.5% larger than the original, assuming printing with ASA, which shrinks relatively much after cooling.
I uploaded the original file, which I created to the exact dimensions. I printed it using CC3D's ASA, and by scaling it up by 0.5% using the slicer settings, it came out pretty good.
( I have re-uploaded the file with the original dimensions. )
