heart fidget

Heart rings and one solid heart with a golden heart-shaped arrow. Rotate the arrow to enjoy the changing patterns. New V3 update: increase the flexibilty in Z direction. Make the spiral arrow. Now you have twist it, lift it and make it spin. It has fewer rings and is smaller. Attention: The original version has relatively thin walls, so good bed adhesion is required. Alternatively, you may use the 0.8 mm wall version, which doubles the wall thickness for improved print reliability. The 0.8 mm wall v2 version increased the flexibility. And the 0.8 mm wall v2 + 18 rings version added more rings and has the maximum flexibility.
