The prompt
Generate a heavy-duty structural L-bracket for automotive use with a uniform material thickness of 10mm. The Base Plate: The bottom leg should be 120mm long and 45mm wide. It requires two slotted bolt holes (9mm wide and 15mm long) spaced exactly 45mm apart center-to-center. These slots must NOT be centered on the plate; they must be offset to one side, positioned so their centerlines are 12mm from the right-side long edge of the plate. The Vertical Leg: The vertical leg should rise 90 degrees from the base plate and be 90mm tall and 45mm wide. Center a single 10mm circular hole exactly 15mm down from the top edge of this vertical leg to mount an LED light pod. The Integrated Support Arm: To replace a bolt-on brace, integrate a solid, forward-facing horizontal support arm extending directly from the front face of the vertical leg. Position this arm 45mm up from the bottom of the base plate. It should project horizontally forward by 65mm, be 30mm wide, and 10mm thick. The bottom face of this arm must be flat so adhesive rubber bump-stops can be attached to rest on the vehicle's bumper. Structural Gussets: Generate two triangular support gussets, each 8mm thick. Place the first gusset connecting the base plate and the vertical leg in the inside corner of the main bend. Place the second gusset connecting the top of the integrated support arm to the upper section of the vertical leg. Ensure neither gusset obstructs the bolt holes.
