The original model is a 3D-printed helmet, which is coated in XTC-3D epoxy to make a smooth surface for capturing the mold. In Part 2, we go through the process of creating a lightweight epoxy support shell for this mold, then hand rotate an impact-resistant finished casting, ideal for cosplay or display:
