Friction-Lock Ball Joint Gimbal
A print-in-place ball-and-socket gimbal for cameras, lidar pucks and sensor boards on a robot or drone frame: a Ø20 mm ball captured in a spherical socket with a 0.4 mm gap gives 360° pan and roughly ±33° tilt, and one M4 thumbscrew driven into a brass heat-set insert (5.5 mm bore) locks the angle without any springs or shims. The 50 x 34 x 5 mm base bolts down with four M3 screws on a 42 x 24 mm pattern, and the 26 x 26 mm top plate carries four M3 clearance holes on a 18 x 18 mm square; overall 50 x 34 x 48 mm.
