StiltbeastStudios walks through the process of building a silicone cup mold — also known as a stack or box mold — designed for casting resin prop parts. The tutorial covers the core workflow used in professional and semi-professional prop fabrication environments. Gel-10 silicone is the featured mold-making material, paired with a compatible casting resin system. This is a practical, technique-focused demonstration suited to prop makers looking to produce repeatable resin pieces.
