I need a snug-fitting enclosure designed for a PCB whose dimensions were entered as “605030.” The housing must be molded in plastic and finished in black. My goal is to receive a production-ready 3D model (STEP preferred) along with a quick render that shows exterior appearance and how the board will be seated inside. If any fasteners are required, include their specs in the model. Once I review the file, I may request one round of minor adjustments before sign-off. Final Price offers only; don't start increasing over time.
