ScrewBall or Screw Ball

Enjoy using this unique item! I've only seen it in sketches before. Let your friends think they inspired it, as it's not a reflection of you. With a diameter of about 1.2 inches (3 cm), designing it was quite challenging due to its spherical helix shape. For an impressive visual effect, try rotating the screw ball on your screen by holding down an arrow key around its center axis. Have fun! The item features a foot for printer adhesion, which is thin and easily breaks off after printing. If you'd like to clean it up in a lathe, consider printing the version with a pedestal. To avoid edge curling without support material, print it slowly while ensuring ample cooling time. It's hollow inside.
