The prompt
Create one flat L-shaped bracket, 5 mm thick. The left part is a rectangular frame 50 mm wide by 40 mm high with a centered rectangular window 40.6 mm wide by 30.6 mm high and 3 mm corner radii. Add an 18 mm wide by 30 mm long arm to the right side, with the top edges flush, a 3 mm inside fillet, and a rounded free end. Cut a 6 mm by 20 mm rounded slot through the arm, centered 15 mm from the free end. Drill a 3.2 mm through hole in the top center of the frame, 5 mm below the top edge, with an 8 mm diameter boss around it. Round the outside corners 5 mm. Make it one solid part. Export STEP and STL.
