RapidDraft synthetic FreeCAD prompt¶

    Candidate: Hot-melt nozzle mounting bracket with heat shield
    Pilot: WEBASTO
    Revision: REV A
    Material: Stainless steel

    Generate a mechanically plausible, feature-rich FreeCAD part that looks like a realistic engineering demo asset instead of a generic primitive.

    Base geometry:
    Sheet-metal style bracket with nozzle carrier, stand-offs, and perforated shield.

    Key features:
    - carrier plate

vertical support leg
heat shield panel
adjustment slots
ventilation holes
```
Critical dimensions:
- Bracket 180 x 120 x 2 mm
```
- Shield 220 x 160 x 1.5 mm
- Nozzle centerline shifts by about 3 mm
  
  Revision intent: Generate the baseline release candidate without the documented follow-up change.
  
  Documented Rev B delta: - Shift the nozzle centerline by 3 mm. - Expand the adjustment-slot range and add locating holes. - Add extra shield ventilation holes for the revised heat profile.
  
  Realism rules: - Keep the geometry manufacturable and parametric-looking. - Preserve the overall part identity between revisions. - Make the revision change obvious enough for RapidDraft diff and release-review storytelling. - Export a single STEP-compatible solid or compound. - Avoid customer-specific IP and treat this as a synthetic review artifact.
  
  Output contract: - Write a standalone FreeCAD Python script. - The script must export the final STEP file to sys.argv[1]. - Keep the script headless-safe.
