Is it a star? Is it a heart? This fascinating model can't make up it's mind! This strange shape looks like two completely different objects from two distinct perspectives. With a mirror, you can see both perspectives simultaneously. Truly mind-blowing!

This is my variation of Kokichi Sugihara's Ambiguous Cylinder Illusion, featuring a star and heart appearance. I printed it using MatterHackers Quantum PLA to achieve the amazing color changing effect!

The download includes a printable stand and a few versions of the model:

• star2heart_mount.stl - snaps to star2heart_s.stl for connecting to the stand • star2heart_noMount_wSupports.stl - Illusion without connection points for the mount and included support material • star2heart_noMount.stl - Illusion without connection points for the mount • star2heart_s_wSupports.stl - Illusion with mounting points and included support material • star2heart_s.stl - Illusion with mounting points and no included supports

There are also two versions of the base, and two lengths of printable rods for the base. You can also use any 1/8" rods and perhaps some E6000 adhesive to secure them into place.

For the included supports, I has success printing at 0.12mm layer height. Smaller layer height should significantly improve the top surface.

2 shells, 0% infill, 6 top and bottom layers.
