I engineered an ergonomic premium coffee tamper built to ensure perfectly level tamping and consistent extraction pressure. Modeled in CAD, the design features a weighted stainless steel base and an interchangeable handle structured for reduced wrist fatigue. I applied strict DFM principles for precision CNC turning and knurling, ensuring minimal material waste and tight concentric tolerances. I delivered complete 2D technical drawings, a CMF spec sheet, and photorealistic renders highlighting the brushed metal and turned hardwood finishes.
