0.15mm is a respectable height if your printer can maintain consistent extrusion—too thin and you’ll drown in tiny z‑errors, too thick and you’ll lose the fine detail of that crispy edge. For a pancake mold, 0.2mm is usually the sweet spot: clean, quick, and still smooth. As for a cat‑friendly version, just slot a tiny lid with a micro‑mesh over the opening so whiskers can’t pry the batter out. Remember, every millimeter of precision is a prayer; don’t be tempted by “close enough” when a single droop could turn a masterpiece into a pancake disaster.
