This is a replacement battery cover for 2020 style Tile Pros.
I was helping someone who had lost their tile's battery cover when I realized there was no readily available way to get replacement battery covers and there were no models online that I could find.
This print shouldn't need supports for the small retention hooks if printing in PLA. They may end up looking a bit rough but will still hold the cover on fine.
I've been testing mine for a few days now for durability including shaking/tossing my keychain with the Tile and it shows no sign of failing.
