I will send you a clear hand-sketch and the specific standards these two enclosure parts must follow. From that, I need manufacturing-ready 3D CAD models created in SolidWorks or exported as STEP files—your choice—as long as the geometry and bend details match the sketch exactly. • Part 1: “G Ring Keep” – a simple 200 mm × 50 mm strip, 10 mm thick. • Part 2: Circular ring – Ø130 mm overall, 60 mm wide. Both parts must be delivered as separate native SolidWorks (.sldprt) files, with matching .step versions. Because they will be used as an outer casing, I’d like your guidance on reasonable sheet-metal tolerances so the assemblies can be produced without fit issues. When you reply, let me know how many similar sheet-metal components you have modeled before, how soon you can turn these two around, and your fixed price. The job is straightforward, so speed and accuracy are the priorities.
