This is a 3d printed mold designed based on https://www.printables.com/model/382059-happy-ditto
Ditto should be very soft, so I made a 3d printed mold for Ditto and poured silicone into it.
I added a little bit of red coloring(for silicone use) to make it appear pink.
The mold needs nearly 200g of silicone to make a full-sized Ditto. I only poured around 160g, so there are still some space between the silicone and the mold.
Mold_a and mold_b mates precisely with three round pins and dimples designed into the mold. V-shaped edges between mold_a and mold_b is for filling clay to seal the gaps and also for demolding using wedge-shaped tool.
