Butterfly Coaster Mold, 4.5 in Concrete or Plaster Coaster, No Supports

A mold for a 4.5 in square coaster with a raised butterfly on its face, about 1/2 in thick. Print it in PLA, pour plaster or cement, let it cure, then flex the mold and lift the coaster out. The butterfly's outline, wing veins, spots and antennae cast as crisp grooves. Every wall and rib is drafted so the coaster releases cleanly. The full-size 5 in butterfly stepping-stone mold, with photos of a real cast, is at https://shop.ash10.dev/p/model-3d-butterfly-paver-mold-emoa?utm_source=cults3d&utm…
