My daughter wanted a gift for her classmates for Valentine's day, so I whipped up this heart with a message on it. She liked it, so I thought I'd post it for everyone.

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"

Customize and print. I used standard setting on Makerware and a Replicator 2.
