Animatronic Eyeball
A Ø30 mm eyeball for the 'SG90 Animatronic Eye Mechanism' kit (print ×2). It prints standing on its flat Ø25.4 mm rear face. The side flats sit 29 mm apart and each has a Ø2.6 × 8 mm self-tap bore for the M3x12 SHCS tilt pins through the gimbal yoke. A Ø2.6 × 12 mm rear bore takes the M3x35 stalk screw that the tilt paddle steers. On the front is a dished Ø12 mm iris and a Ø5 mm pupil recess, ready for paint or a sticker.
