I developed an ergonomic, high-performance fishing rod handle optimized for wet-grip traction and long-term durability. Using precision CAD modeling, I integrated a reliable threaded reel seat, weight-reducing split-grip geometry, and tactile slip-resistant surfaces. The entire assembly was engineered around DFM principles for dual-shot injection molding and EVA foam compression. The final handover included factory-ready 3D files and realistic renders showcasing the premium textured finishes.
