This is a remix of my customizable heart message (http://www.thingiverse.com/thing:247436/) with the ability to add a loop for a necklace or a charm bracelet.
I made it customizable so you can put in whatever message you want.
In case you don't want to customize, I've uploaded stl's of "I love you" and "My friend"
