Microfilter housing, rotary clip alignment

[PotOdds]

I just replaced my cabin filters today. One of things that I'm trying to make sure is installed correctly, is the 7 rotary clips that hold the microfilter housing in place. I'll probably do a step and step and figure it out myself but was hoping there was some kind of diagram that showed the correct alignment.

I mainly used this video as a guide to change the cabin filters but it doesn't really show the rotary clip alignment except to say "do a quarter turn". The problem is that you can rotate it fully 360 degrees. Tough to see how the clips hold onto the frame.
