This is a small necklace pendant! All you will need is a necklace chain! A split ring will help the pendant sit on your chest a little bit better, if you have any available.

Prints very easily: I printed with a .4 nozzle PLA on my ender 3

You might have to hit it with a hairdryer to clean up stringing, but out of the 3 prints I have of this model, only 1 of them had some stringing. Enjoy!
