Lego Heart Necklace, thinner

I really liked the original Lego Heart by IPadNanito. (http://www.thingiverse.com/thing:106872) but, I wanted it more streamlined and thinner. I'm planning to print a few dozen of these for my son's valentines.

Of note, the Brickheart_thin files are very tight at .2mm clearance. The Brickheart_thin.3 and BrickHeart_thin.4 files are an attempt to add more clearance between the peg and hole. .3mm and .4mm respectively. I'm finding the easiest snap together and separation on the .4 at 90% extrusion multiplier. Your printer may vary.
