OK emoji charm for 3d printing. Originally I created a similar model on another 3d models platform, but it was not suitable for 3d printing. But this model is for printing. It also has custom adjustable parameters for form and shape in the attached blender file with easy to use sliders. Manifold all quad topology ready for subdivision and deformation.
