Stewart Top Payload Platform
This is the moving top plate of the 'MG90S Six-Servo Stewart Platform' kit. It is 130 mm across and 5 mm thick, with six M3 clearance holes on a 50 mm radius (pairs at 30°, 150° and 270°, ±12°). Each hole has a captive M3 hex-nut pocket, so the ball-stud tabs of the six pushrods bolt on from below with M3x16 screws. The centre has a 31 x 31 mm M3 payload grid with nut pockets. Three triangular windows save weight, and a 4 mm underside ring rib at 58 mm radius stiffens the plate. The rib is cut away wherever a stud tab sits. The plate prints top-face-down with the rib pointing up, so it needs no supports.
