Parametric L-Bracket

Create a precise 3D parametric CAD model of an L-shaped mechanical mounting bracket. Engineering specifications: Base plate: 80 mm long, 40 mm wide, 5 mm thick. Vertical plate: 40 mm wide, 50 mm tall, 5 mm thick. Two circular mounting holes on the horizontal plate, each with a diameter of 6 mm. Two circular mounting holes on the vertical plate, each with a diameter of 6 mm. All holes must pass completely through their respective plates. Keep the holes symmetrically positioned and sufficiently far from the edges. Add 3 mm fillets to the outer corners where geometrically appropriate. Use millimeters as the unit system. Generate a single solid body with accurate dimensions. Preserve an editable parametric feature history if supported. Show an isometric view of the finished model. Do not add decorative features. Prioritize geometric accuracy, symmetry, and a clean mechanical design.

Parameters

Every value above is a live dimension. Open a model like this in the editor and each one becomes a slider you can drag before exporting.
