walnut 3d model

Create a 3D cookie cutter based on a Chilean walnut (Juglans regia). Shape: natural walnut shell, slightly asymmetrical, oval form with organic curves. Front detail: include a central seam dividing the walnut into two halves. Surface: add shallow organic grooves to mimic the natural wrinkled texture, but keep it simplified for easy cleaning.

Specifications: - Wall thickness: 1.2 mm - Height: 15 mm - Cutting edge: 0.4 mm sharp edge - Add a thicker top rim for comfortable pressing - Avoid deep crevices that trap dough Ensure the model is optimized for 3D printing (PLA or PETG) and baking use. Output: STL
