AirTag Case (Screwable)

This is an AirTag case that is screwable and can be used to attach an AirTag to any surface if you use double sided tape (e.g., recommend [this one](https://www.amazon.com/dp/B093PZHX9P) ).

Improvements:

1. Increased the thickness of the base to improve grip
2. Increased the tolerance on the threads to make it easier to close and open
3. Added an anti-rattle feature
