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.
Printing: open side up, no supports, 0.2 mm layers, 15% infill, 2-3 walls. About 1 h 20 min and 58 g of PLA on any FDM printer with a 0.4 mm nozzle (times vary by printer).
Casting: coat the cavity with a thin layer of release agent (mold release spray, petroleum jelly or diluted dish soap) before every pour. Mix plaster or cement to a pourable, lump-free consistency, pour, and tap the mold on the table for a minute to bring up bubbles. Let it cure fully before demolding (plaster 1-2 h, cement 24-48 h), then flex the walls outward and lift. Add felt pads underneath so it doesn't scratch the table.
