Spirograph heart (or cat, or kidney shape, or smile)
thingiverse
My kid scored a heart-shaped spirograph toy from a gift pack at the cinema. But after exiting the movie theater, he forgot his toy at the eatery and was devastated, as if his heart had actually been broken. I stepped in to save the day by crafting a new shape for him using the smaller gears of this thing: http://www.thingiverse.com/thing:252162. If you're looking for a (nearly) heart-shaped spirograph, help yourself!
