Twin Ball-Joint Pushrod
This is the print-in-place 100 mm pushrod for the 'MG90S Six-Servo Stewart Platform' kit (print ×6). It prints as three pieces: a 7 × 12 mm rod with a cupped socket at each end (11.0 mm spherical bore, 7.5 mm throat) and two captive 10 mm ball studs. Each stud has a 4 mm neck and a 12 × 3 mm tab with an M3 clearance hole 9 mm from the ball centre. Bolt one tab to the crank with an M3x16 and a nylock nut, and the other to the platform. The studs spin freely and tilt about ±20° with no loose ball links. Overall size is about 130 × 21 × 14.5 mm.
Print-In-Place M5 Heim Rod End
This rod end prints in one go with a 16 mm ball already captured inside a 23 mm eye. The ball has a 5.5 mm M5 clearance bore. The 46 mm body has an in-line 5.5 mm bore and a drop-in M5 nut pocket, so it threads onto M5 rod. It's meant as a cheap, repeatable ball link for Stewart platforms, delta arms and parallel-kinematic robots, where you'd otherwise be press-fitting loose balls into printed sockets.
