RapidDraft synthetic FreeCAD prompt¶

    Candidate: Product inserter pusher sled
    Pilot: WEBASTO
    Revision: REV B
    Material: Al 6082-T6

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

    Base geometry:
    Compact machined sled on guides with pusher-face mounting pattern and cable-relief detail.

    Key features:
    - guide mounting holes

belt-clamp relief
pusher mounting holes
dowel locations
cable-relief notch
```
Critical dimensions:
- 180 x 90 x 35 mm
```
- Thickness changes from 30 to 35 mm
- Pusher holes move by 5 mm
  
  Revision intent: Generate the changed follow-up revision and make the revision delta mechanically visible.
  
  Documented Rev B delta: - Increase the body thickness from 30 mm to 35 mm. - Add dowel locations for repeatable pusher mounting. - Shift the pusher-hole pattern by 5 mm and add a cable-relief notch.
  
  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.
