The prompt
Create a 3D assembly of an automatic sorting station. Units: mm. Each component is a separate named solid. Export STEP. COORDINATES: origin on the floor under the belt centre at the idler roller. X = along the belt, Y = across the belt (motor side = +Y), Z = up. 1) CONVEYOR - Frame: two 20x20 aluminium profiles, 460 mm long along X, at y=+68 and y=-68, z 0..20. - Two rollers, diameter 40 mm, length 100 mm, axes along Y at z=64, at x=0 (idler) and x=400 (drive). Centre distance exactly 400 mm. - Two steel shafts diameter 8 mm through the rollers, 150 mm long. - Belt: closed loop around the rollers, 1.5 mm thick, 98 mm wide. - Four pillow blocks (base plate 60x30x4 with slotted holes, body with a 22 mm bearing bore at z=64) on the profiles, with 608 bearings. - DC gearmotor (37 mm diameter, 80 mm long, 6 mm shaft) at the drive side, axis along Y at x=400, linked to the shaft by a flexible coupling 14x25 mm, on an L-shaped steel plate. 2) CAMERA GANTRY (at belt middle, x=200) - Two vertical 20x20 profiles, 800 mm high, at y=+95 and y=-95, with a 20x20 crossbeam on top along Y. - A vertical 20x20 mast under the beam at y=0, down to z=200. - Sliding square clamp (inner 20.4 mm, wall 4 mm, height 40 mm) on the mast, carrying a 3D-printed ESP32-CAM box 33x45x16 mm. - Lens hole diameter 10 mm, pointing straight down, at z=220. 3) SLIDER-CRANK PUSHER (at x=300, +Y side, motion along Y) - Two guide rods diameter 8 mm, 150 mm long, 28 mm apart, at z=130. - Crank disc diameter 50 mm, crank pin at 20 mm from the centre (stroke = 40 mm). - Connecting rod 70 mm between hole centres. - Slider block 30x40x16 mm sliding on the rods, with a flat pusher plate 40x45x3 mm just above the belt (z=88). - Small DC gearmotor diameter 25 mm drives the crank. 4) BINS AND ELECTRONICS - Open box "Bin_Reject" 120x90x70 mm at y -170..-80, x 240..360, and "Bin_Good" 120x100x70 mm at the end of the belt, x 440..560. - Electronics box 150x100x50 mm with ESP32, PWM driver and 12 V supply, on the floor at x -250..-100, y 40..140. Colours: profiles grey, printed parts blue, belt black, motor dark grey, bins orange.
