Door Handle 3D CAD Model

I have a photograph of a contemporary door handle and now need it translated into a clean, production-ready 3D file. The model should capture the medium level of detail visible in the image—overall shape, screw holes, chamfers, subtle curves.

Purpose
The files will feed directly into our manufacturing workflow, so accuracy is vital. I will supply precise measurements (length, diameter of mounting holes, spacing, etc.) as a reference; use those dimensions to keep the model fully parametric and ready for CNC or mould tooling.

Preferred approach
SolidWorks, Inventor, Fusion 360, or any comparable CAD platform is fine as long as you can export both formats below.

Deliverables
• STEP file (.step) suitable for machining
• STL file (.stl) for quick fit checks and printing

Acceptance
The finished STEP will open without feature errors, all key dimensions will match the drawing I provide (±0.2 mm tolerance), and surfaces will be watertight in the STL.

The distance between the legs should be about 8", overal end-to-end height should be about 15", the diameter of the legs should be about 0.75"-1". The diameter of the handle body should be in the range of 0.5"-1.5".

Turnaround is flexible for a quality result, but a quick update once the first pass is ready would be appreciated so I can verify measurements before you finalise fillets or mounting geometry.
