Final sculpt and setting up for the moulding process. 

Top Left: First step was to embed the scultpure, for this I used a product called Insta Mold. Top Right: After embedding I built up the walls of the mould and poured in the Pinkysil. Bottom Left: After curing, I flipped the mould over and removed the lego walls down to the level of the rubber. Bottom Right: After removing the embedding compound and cleaning, I built up the walls again for the second part of the mould. 

Finished mould.
