Steel-Pinned Print-In-Place Knuckle Link
A two-link knuckle joint that prints already assembled: a 12 mm tongue turns on a 10 mm printed pin between clevis cheeks, with 0.5 mm clearance all round. The pin has a 4.1 mm bore, so you can push a 4 mm steel dowel through it for extra stiffness. Each 24 x 8 mm arm has four M3 clearance holes on a 10 x 12 mm pattern for bolting to robot arms, legs or linkages, and the tongue's fillet acts as a hard stop when the link is straight.
Linear Actuator Swivel Clevis Mount
A print-in-place two-axis end mount for 12 V linear actuators: a 64 x 56 mm base flange with four M5 clearance holes carries a captured swivel yoke that yaws a full 360° on a printed post, while a 22 mm wide clevis with an 8.5 mm cross bore takes the actuator's own 8 mm rod-end pin 19 mm above the mounting face. It replaces the brand-specific bracket-and-pin kits that cost as much as the actuator, and the free yaw axis stops cheap actuators from binding on vent flaps, coop doors, gates and solar trackers. Overall 64 x 56 x 36 mm; the yoke and base print as one piece with 0.4–0.5 mm running clearance and cannot be pulled apart.
