CWWK soft router 6 i226 ports faces

As I added 4 ssd inside the case, I wanted a way to add more air circulation on the inside without adding a fan (no more place). So I designed new faces with grid. Sorry, the design is not well oriented. But the good orientation is obvious ;-) I advise to print it in a thermal resistant filament. Maybe avoid PLA. I personally use esun ABS+
