This is a pair of heart shaped gears. You can see the movie to find how does it works. The gear is basically a non-circular gear (NCG) .

When you look at the shape of a heart, you will find that there is a tip and a pit. "they can match", when the idea flashed through my mind, I realize that I can design a pair of gears with same heart shape(I'm major in mechanical engineering), and here is it, a pair of eardrops(without hooks).

I think it is a good idea to give such a gift to your lover. It is a perfect annotation of "My heart follows you".

If you want the gears turn like in the video, you need to order the axis pair and drill two d=2mm holes of distance = 16.5mm on a base by yourself.


IN: 0.674 w x 0.666 d x 0.472 h
CM: 1.712 w x 1.692 d x 1.2 h

Hi ChristianA, If you want of make this part of a necklace. I recomment you to check the bigger one( That one have a word"love" in the heart and the letter "o" is used as the axlehole of the gear. I've already put a small lacing hole at the side of the top tooth of the gear in the design.

It would be really great to make this part of a necklace or bracelet. Any plans for that?
