Today is Mother's Day, so what better way to show Mom you love her than by 3D printing her a unique piece of jewelry from the comfort of your own home? Designed by two men who formed a collaboration called 3DNA, you can now download and 3D print an incredible geared heart pendant that features 4 working gears all turned using a separate key that can be placed on your keychain. So perhaps this Mother's Day you can forget the conventional Dinner, Chocolates, and Flowers and give her a 3D printed necklace charm.
