Mesh rebuild freecad bracket

The request

I've attached an STL of an L-bracket exported from a CAD application. Rebuild it as a clean parametric part: one sub-part named exactly `bracket`, matching the mesh's dimensions, hole positions and slots, and standing in the same place as the mesh (Z up, same origin — build it where the import sits, don't re-centre it). Give it three controls — `width`, `thickness` and `holeDiameter` — whose defaults match the mesh and whose ranges cover ±10 mm, 2–8 mm and 3–8 mm. Keep the mesh imported in the part while you work. Measure the mesh first; do not guess.

What the AI judge checks

• The overall form matches the reference: the same kind of object, the same silhouette from the matching angle
• Proportions match: the relative sizes of the major dimensions agree with the reference within what the eye can judge
• Every major feature visible in the reference (holes, slots, bosses, tabs, lips) is present in the result
• Those features sit where the reference has them
• Nothing is present that the reference does not show — no decorative or unexplained geometry
• Edges are straight and faces are flat — a CAD rebuild, not a copy of the mesh's facets
• The slots are elongated openings, not round holes

Measured checks

• one sub-part named bracket (gate)
• volume within 3 % of the mesh (gate)
• bounding box within 0.5 mm of the mesh (gate)
• symmetric difference under the measured floor
• holes match the mesh
• the imported bracket is still declared as an import
• asked the oracle at most once
