I get super annoyed when I accidentally hit the button on my tile and trigger the “find my phone” feature. I turned off the feature for my tile so it can't even find my phone, but that doesn't change it's behavior of beeping loudly from my pocket. This is a snap-on cover to prevent accidentally pushing the button in my pocket. There are at least two other, similar models in makerworld, but this one is minimalist while not requiring glueing, so you can still hit the find my phone button if you want to.

I've printed it once with PLA and have not stress tested it yet, so there may be improvements coming if it breaks or snaps off easily.
