I have an early-stage product idea that now needs a clean, accurate 3D model suitable for concept-level prototyping. At this point I want to explore form, proportions, and basic part relationships rather than final engineering detail, so I’m looking for a modeller who can translate my sketches and reference photos into a watertight digital file. Here’s what the project involves: • Build a product-grade 3D model that reflects the overall shape and key features shown in my references. • Keep geometry clean and optimised so it can be taken straight into rapid prototyping (STL or STEP preferred). • Supply the native file (Fusion 360, SolidWorks, or similar) plus a universally readable export. • Include a couple of simple shaded renders so I can review aesthetics before approving the final file. Because this is a concept prototype, minor creative input on ergonomic tweaks or manufacturing feasibility is welcome, but the main goal is a solid, presentable model I can hand to a printer or CNC shop for the first physical mock-up. Let me know which software you plan to use and share any relevant portfolio samples of comparable product work. If you need additional dimensions or clarifications, I’m available to respond quickly so we can keep the turnaround tight.
