Case for Chipolo

My broke after years of use, so I built a simple model to replace it.
 

Installation step

1. Remove the battery lid / the speaker side housing. 
   • Since mine was broken, it was easy to remove it from the broken part. You can refer to the video https://www.youtube.com/watch?v=LFRb7fc926I to remove the other side of the housing. (I'm not the author of the video, so please let me know if I've missed any links.)
2. Test and confirm that it still is functional with only the middle part.
   •  [To secure the speakers] I think the speakers can come loose easily, so I also lengthened the pins of the speakers by hand to make sure the speakers have a good connection with the motherboard. 
3.  Slide the middle part onto the replacement case.
   • Inside there are two bars on one side is the speaker side, also used to secure the motherboard and speakers.
4.  Install the clip.
