ketupat 3d model

Design a 3D printable CAD model of a Ketupat (traditional Southeast Asian woven rice dumpling) with the following specifications: Overall shape: Symmetrical diamond (rhombus) form based on a cube rotated 45 degrees. Dimensions: 80 mm height × 80 mm width × 80 mm depth. Wall thickness: 2.5 mm (suitable for FDM 3D printing). Surface design: Embossed woven pattern mimicking traditional palm leaf weaving. The weave should appear interlaced, with alternating over-under strips, each strip approximately 8 mm wide and 1.5 mm raised from the base surface. Structure: Hollow interior to reduce material usage. Top feature: Two flat woven “leaf tail” extensions (100 mm length, 15 mm width, 3 mm thickness) emerging from one vertex, slightly curved for realism. Bottom: Small 10 mm diameter hidden drainage hole (optional, for functional container use). Edges: Slight 2 mm fillet on all main edges for smooth printing. Printing considerations: No supports required. Overhang angles no greater t
