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.

IIRC the clips rotate 90 degrees only and have two small triangles that align when locked... on 2010 at least.

2 triangles? Not sure I see it. But anyway, you can definitely rotate the clips more than 90 degrees. I got it to clip on but one of the clips was a pain. I was going by feel and it was never fully engaging. Finally got it to after 15 tries. Definitely not a full proof system.

these triangles

I really appreciate that picture. I was using a flashlight but didn't really see those triangles. I will definitely give it another closer look.
