I need a precise 3D model of a rectangular nameplate that I can send straight to the printer. The outside dimensions are 112 mm × 70 mm, the corners are cut off so each one forms a clean angle, and the overall edge thickness is 2 mm. At each short end sits a mounting hole—diameter and exact offsets are already worked out, and I’ll pass those figures to you as soon as we start. A second version of the plate is also required: the same outline and 2 mm outer rim, but stepped down to 1 mm thickness over a central area recessed 12 mm in from every side. Think of it as a two-layer panel—rigid around the edges, thinner in the middle. I have pdf files of exact measurements you need to build/mode/ stl file for 3d printer as long as the finished product is delivered as clean, watertight STL(s). Deliverables: • Print-ready STL for the standard 2 mm plate • Print-ready STL for the stepped-thickness plate • Quick screenshots or viewport captures that verify dimensions, hole diameters, and hole placement Acceptance criteria: no non-manifold edges, dimensions within ±0.1 mm, and both models open flawlessly in common slicers such as Cura or PrusaSlicer. If everything lines up with the measurements provided, the project is complete.
