1. Print the Mold Maker on
a 3D Printer
Print the mold form on a 3D printer
(
Figure 21-5
). For people printing on their 3D
printers at home, I recommend printing the
Chocolate Skull Mold Maker with 13% infill
and three shells. I have provided two ver-
sions of the Chocolate Mold Maker STL file,
one with thin walls (1.3 mm) and one with
thicker walls (2.3 mm). The one with thin
walls is not completely watertight if you print
it with a raft. I used liquid tape on the bottom
to make it water tight, but in the end the
rubber mold mix was very thick and I don't
think the liquid tape was actually necessary.

The thicker one will take much longer to
print. The thin-walled one should be fine to
pour the silicone rubber into.
2. Mix and Pour the
Smooth-Sil 940
Take the Smooth On Smooth-Sil 940 food-
safe silicone rubber (
Figure 21-6
) and mix it
according to the proportions on the pack-
age. Pour it into the 3D-printed chocolate
Design Your Own Mold in OpenSCAD
If you want to design your own mold instead of using
the skull mold file included with the
Chocolate Skull
Mold Maker
,
you can edit
skullCandyMold.scad
to use
your own object.
Here's a render of the mold maker in OpenSCAD:
I designed this mold using a mashup of an Open-
SCAD parametric box (by Thingiverse user
acker
) and
my scanned skull.
Before you make any changes, I suggest that you play
around with the mold code as is. For that to work,
make sure the
vampireSkull_0.2.stl
is located in the
same directory as the OpenSCAD file.
Once you're sure it's working, you can substitute your
own STL for the mold: just change the “filename”
variable to the name of your STL. Make sure your STL
is in the same directory as the
.scad
file.
