This is a spinoff of Den_484447 great low poly heart. I scaled the model to the perfect size to work as a kid's maraca. I printed this off to give to my kid's class. 

I printed with 3 walls, 0% infill, painted on supports for 30-degree overhangs, I put a pause in the print about 80% of the way done, added a tablespoon of rice inside the print, then resumed the print. 

I hope you enjoy this as much as my kids do.
