A client approached me with an urgent challenge their smart fitness tracker had a validated PCB but no production ready enclosure. Working from their component STEP files and a rough concept sketch, I designed a fully ergonomic wearable housing in Fusion 360 within 7 days. The enclosure featured precision PCB fitment with 0.2mm tolerance, snap fit assembly, silicone overmold zones for skin comfort, and draft angles optimized for injection molding. I delivered fully editable Fusion 360 source files, STEP exports, and a complete DFM report. NovaTech successfully submitted the design to their Chinese manufacturer with zero revision requests moving directly into tooling production on schedule.
