Structural Mounting Bracket (5-Segment Spine with U-Channel Walls)

Create a complex structural mounting bracket with a main spine thickness of 10mm and a uniform width of 45mm. Segment 1 (Base Plate): A horizontal segment 60mm long. It contains two slotted holes (9mm wide by 15mm long) spaced exactly 45mm apart center-to-center. These slots are offset, centered 12mm from the right-side edge of the plate. Segment 2 (Lower Riser): Rises 90 degrees straight up from the front edge of Segment 1. It is 40mm tall. Place a 10mm thick triangular support gusset in the inside corner between Segment 1 and Segment 2. Segment 3 (Middle Shelf & Bumper Brace): Extends 90 degrees forward from the top of Segment 2. It is 100mm long in total. The front half of this shelf will act as a resting brace. Segment 4 (Upper Riser): Rises 90 degrees straight up from the top face of Segment 3. Instead of being at the end, it originates exactly in the middle of Segment 3 (50mm away from Segment 2). It is 50mm tall. Segment 5 (Light Mount Shelf): Extends 90 degrees forward from the top of Segment 4. It is 45mm long. Place a 10mm circular hole dead center. Place two smaller 6mm circular holes positioned 15mm to the left and 15mm to the right of the center hole. Side Wall Reinforcements: To box in the structure, generate two vertical side walls, each 6mm thick. These walls should be attached to the left and right outer edges of Segment 3, Segment 4, and Segment 5. They must connect the top face of the Middle Shelf (Segment 3) flush up to the bottom face of the Light Mount Shelf (Segment 5), completely flanking the Upper Riser (Segment 4) and forming a rigid U-channel.
