Morphing Skewer with Reuleaux Transition

Create a **smooth, continuous 3D transition along the skewer's longitudinal axis**. The geometry must change gradually in this exact order: **pointed tip → Reuleaux-triangle section → flat rectangular section** Do **not** make these three sections meet with sharp steps, shoulders, or abrupt changes. 1. Start with the **pointed end/tip**. 2. From the pointed tip, **gradually and smoothly increase the cross-sectional shape until it becomes a Reuleaux triangle with a constant width of 2.80 mm**. 3. Continue the same smooth transition from the **2.80 mm Reuleaux-triangle cross-section into the flat rectangular section**, gradually widening and flattening it until it becomes exactly **4.20 mm wide × 0.70 mm thick**. 4. The transitions must be **blended/lofted continuously**, with no sudden change in width, thickness, or curvature. 5. The final result should look like **one continuous piece of metal that smoothly morphs from one cross-section into the next**, rather than separate pieces connected together. 6. Keep the entire transition **within the existing 20 mm end section**; do not add any extra length. The same transition must be mirrored at the opposite end of the skewer.
