Chocolate mold - Hart

I had a mini project in mind for valentines day.  Engraving on chocolate. I did'nt have any flat surface harts so i improvised by 3D printing one.  

I designed the mold in angle so it would be easier to unmold because of the 3D printed layer texture.  I put a little olive oil on the mold before pouring the chocolate.
