OOONO No.1 holder for BMW F21/F22

A simple holder for OOONO No.1 on the room mirror bracket cover of BMW F21/F22. 

It can be printed the side face down, and I recommend to use some 1mm thickness form tape in between the holder and the OOONO No.1 to stabilize it. 
This way, I was able to eliminate the annoying rattling noise that used to happen at some specific speed range.

The holder can be attached using some double sided tape on the cover of the room mirror covers. Then it will be away from your view, yet easy to notice when the alarm beeps and the LED lights up.
