I added four sphere cuts to represent chambers, and these inside cuts are not anatomically correct. Basic Set: (Best for chocolates or other small items under 36mm) * The base part "Heart_Base06.stl" requires supports. I used a max overhang of 65 degrees, and it worked out fine. * The top part "Heart_Top04.stl" can be printed safely without supports and has four basic 36mm hemisphere cuts to match the bottom. Stem Set: I made a STEM project-friendly set that allows wires to be run down the stem to the base, a wider cut on the top hemisphere for project space, small wire grooves, and guides on the sides. * The Base "STEM_Heart_Base07.stl" requires supports. I used a max overhang of 65 degrees, and it worked out fine. * The Top "STEM_Heart_Top07.stl" can be printed as oriented. Supports are suggested but optional on this part. If turned on, they may prevent the inside hemisphere cuts from sagging or getting stringy. The circles will fit Rocher candies if you remove the little brown cup paper on the bottom and keep only the gold foil. To fit bigger items or chocolates, scale up. Each sphere cut is 36mm in diameter (about 1.4") by default.
