https://youtu.be/SVWlQuaT4II My 2023 3D printed Valentine for My Valentine! The inner heart hangs from the outer heart using a magnet and metal pin. A small motor in the base rotates a stack of eight neodymium magnets, and a single neodymium magnet in the inner heart reacts by rotating the inner heart with no apparent mechanical connection. As usual, I probably forgot a file or two or who knows what else, so if you have any questions, please do not hesitate to ask as I do make plenty of mistakes.
