The prompt
Create a U-shaped portal frame made from a bent flat bar, 20 mm wide and 4 mm thick, in one single solid. - Outer width of the U: 150 mm. Total height: 200 mm. - Two vertical legs, each 4 mm thick, and one top crossbeam 150 mm long, 4 mm thick. All parts are 20 mm wide (depth). - At the bottom of each leg, a foot plate pointing OUTWARD, 30 mm long x 20 mm wide x 4 mm thick. - In each foot plate, one slotted hole 11 mm long x 5.5 mm wide (for an M5 screw), centered on the plate. - At each inner corner between a leg and the crossbeam, add a small triangular gusset 12 x 12 mm, 20 mm wide. - In the crossbeam, two through-holes of 3.4 mm diameter (for M3 screws), centered on the beam length, spaced 16 mm apart across its width. Units: millimetres. Export STEP.
