I need a precise 3D CAD model of a custom product that can go straight into manufacturing. The geometry must be clean, watertight and built to high-detail standards so the STL slices flawlessly for CNC or additive production. Here’s what I will hand-off to you: • Core reference material: sketches, dimensions and functional notes once we start. • Expected deliverables: the native CAD file (SolidWorks, Fusion 360, Rhino or comparable), a production-ready STL, and a quick viewport render for visual confirmation. Critical points: • Surfaces must remain manifold with no non-planar faces or inverted normals. • Dimensional tolerances need to match the specs I’ll supply—this model is headed directly to the shop floor. • File should open error-free in Cura, PrusaSlicer and a standard CAM workflow. If you have experience preparing high-resolution product models for real-world manufacture, let’s get started—I’m ready to move as soon as you can.
