Structural Mounting Bracket

Create a complex structural mounting bracket with a main spine thickness of 10mm and a uniform overall width of 76mm. Segment 1 (Base Plate): A horizontal segment 55mm long. It contains two slotted holes (9mm wide by 15mm long) spaced exactly 38mm apart center-to-center. To offset the mount, position the center of the first slot 14mm from the right-side edge of the plate, which places the center of the second slot 52mm from the right-side edge. Segment 2 (Lower Riser): Rises 90 degrees straight up from the front edge of Segment 1. It is 36mm 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 90mm long in total. The front half of this shelf will act as a solid resting brace. Segment 4 (Upper Riser): Rises 90 degrees straight up from the top face of Segment 3. It originates exactly in the middle of Segment 3 (45mm away from Segment 2). It is 45mm tall. Segment 5 (Light Mount Shelf): Extends 90 degrees forward from the top of Segment 4. It is 45mm long. Leave this entire top face completely solid with no holes. Side Wall Reinforcements: To box in the structure, generate two vertical side walls, each 8mm 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 76mm wide U-channel.
