It doesn't get more simple than this. In preparation for Valentine's Day, I thought I'd share this quick and easy technique in Blender. The result is a stylized heart with a Mobius-like twist. Since the result is actually a watertight solid shape, this could be exported for 3d printing or used in any number of design projects. If you want to try a 3d print, just keep in mind the scale and thickness values of the object. I haven't illustrated that here, but many of my other videos go into detail about how to set up a scene for modeling to scale for 3d printing. Since the base of this shape is extremely low poly, it can be used in mograph or animation very easily. In fact, the turntable animation example at the beginning was rendered with Eevee in about 2 minutes.
