This mold was made mainly with softer and squishier materials in mind, such as silicone or rubber. 

The final heart is about 6-7cm tall.

The order of the pieces to fill in with the material start with parts 1 to 4, which are then assembled with part 5. The process of time and vulcanization greatly depends on the material being used. To disassemble, the parts are removed in a descending manner; (5,4,3,2,1) following the arrows that are printed on the sides.

The print need supports, just remember to remove them before using the mold.
