Kawaii Bao Bun Plaster Mold
A one-piece mold for casting cute plaster bao buns, designed from scratch from a single photo, in two versions: plain and with a bow.
A mold you pull straight up can't have anything that hooks the plaster, so the design had to work with that. We moved the face onto the gentler slope of the bun instead of its steep sides, and gave the bow a slight taper so every casting pops out clean.
Pour plaster to the rim, scrape it flat, let it set, and flip out a smiling bun. The mold is reusable.
