Every Halloween I make treats to give away. This year I had two 3D printers at my disposal, so I decided to make 3D printed chocolate mold maker. I used food safe silicone to cast the chocolate mold from the 3D printed mold form. Then I cast many, many chocolates.
The skull is from a 3D scan I created using 123D Catch. I used OpenSCAD script to make a mashup of a parametric box by Thingiverse user acker, and my skull to create the mold maker. I also created trays for the chocolates using the parametric box script.
The candy trays were printed in PLA, so they would relatively "food safe" at least compared to ABS. I cast many, many batches of white skull chocolates and then placed them in the PLA trays. I then placed the trays in treat bags and sealed them with twist ties.
The OpenSCAD code and STL files are all available on Thingiverse (and at later steps within this Instructable):
