Precise STL Model for Prototype

I need a top-quality, print-ready STL of a new product prototype. All critical dimensions are already defined, so the job is to translate my drawings into a clean, watertight 3D model that will run flawlessly on any standard FDM or SLA printer. Accuracy matters—I’m using this file for functional fit tests—so please keep tolerances tight, respect wall-thickness notes, and avoid non-manifold edges.

You’re free to work in SolidWorks, Fusion 360, or any professional CAD package as long as the exported STL meets typical requirements (millimetre units, oriented upright, no over-refined mesh). A quick screenshot or low-res proof for approval before final export would be helpful.

Deliverables
• Finished, print-ready STL (manifold, correct scale)
• Native CAD or STEP file for future revisions

If you have experience taking precise specs from paper or PDF into reliable 3D prints, I’d love to work with you.
