I need two separate STL models prepared for 3-D printing. They are simple, single-body functional prototypes that I’ll be using in marketing presentations, so the emphasis is on clean geometry and a professional surface finish rather than intricate internal mechanisms—no moving parts or assemblies are required. I will share rough dimensions and reference images once we begin; you’ll translate those into watertight, error-free STL files ready for FDM or SLA printing. Please make sure wall thicknesses are practical, overhangs are considered, and the files pass a standard slicer check (PrusaSlicer, Cura, or similar). Deliverables: • Two separate, print-ready STL files • A brief note on recommended print orientation and material settings I’m looking for someone who can turn this around quickly and is comfortable fine-tuning prototypes meant to look good in photos and hands-on demos.
