Flip-Symmetric Steering Knuckle
Front steering knuckle for the 'SG90 Ackermann Steering Rover Chassis' kit, 12 mm tall. It has a Ø14 kingpin boss with a 3.4 mm bore for an M3x25 SHCS and nylock, and an 18 mm steering arm set at the 17.6° Ackermann angle, with a Ø10 tip boss and a 3.4 mm hole for the tie bar. The 14 x 13 mm axle block carries an M4x30 axle bolt through a 4.5 mm bore, held by a captured M4 nut. The part is symmetric top to bottom, so print two and flip one over to get the left and right knuckles.
