Mechanical 3D Model for Prototype -- 2

I have a mechanical concept that now needs to leave the sketchbook and become a precise 3D model ready for rapid prototyping. Your main focus will be parametric 3D modelling—no 2D drafting or electrical work is involved.

The model must be production-quality, with accurate clearances, draft angles where appropriate, and assemblies that can be exported as STEP or STL for my preferred SLA printer. I typically work in SolidWorks or Fusion 360, so delivering the native file along with the neutral formats will let me iterate further after review.

Once the model is complete, I will print and verify fit; if minor tweaks are required, I’ll share feedback so you can refine the file before we sign off.
