Bolt-On Bat Wing Frame
This open bat-wing skeleton is part of the 'SG90 Scotch-Yoke Flapping Wing Rig' kit, and you print two. It measures about 150 x 87 mm and is 3 mm thick. The 30 x 14 x 4 mm root pad bolts to the Shoulder Wing Root Rocker with two M3x8 screws into the rocker's heat-set inserts, through 3.4 mm holes 15 mm apart. From the pad, a 6 mm leading-edge spar, three tapered finger spars and a scalloped trailing rib make a frame of about 9 cm³ that you can cover with fabric or foil.
Tilt Axis Idler Pivot Post
This is the idler pivot post for the 'SG90 Animatronic Eye Mechanism' kit. The tilt paddle's left arm turns on an M3x16 SHCS, M3 washer and M3 nylock through the post's Ø3.4 hole at y -45, z 30, directly across from the SG90 tilt servo. The wall is 6 mm thick with a flat inner face and a rounded top, and two gussets brace it. The 4 mm foot (about 20 × 34 × 40 mm overall) has a 3.4 mm slot with end centres 20 mm apart. Two M3x10 SHCS and nuts go through deck holes (-60, -40) and (-60, -50), and the slot lets you slide the post ±5 mm to line it up with the servo shaft. Fit the foot screws without washers so the heads clear the gussets.
Twin-Slot Eye Tilt Paddle
The U-shaped tilt rocker (96 × 37 × 18 mm, black) for the 'SG90 Animatronic Eye Mechanism' kit. It pivots on the y -45 / z 30 axis between an SG90 horn and an M3x16 idler pivot. Its 3 mm crossbar has two 22 × 4.2 mm rounded slots on a 60 mm pitch that steer the M3x35 eye-stalk screws. The right arm has a flat outer face for the stock SG90 horn (2 servo self-tappers) and a Ø7 hole for screwdriver access. The left arm has a Ø3.4 hole for an M3x16 SHCS, washer and nylock.
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.
Animatronic Eye Deck Plate
This is the 140 x 150 x 3 mm base deck for the 'SG90 Animatronic Eye Mechanism' kit. It has a 10 mm grid of Ø3.4 M3 clearance holes, with the eye-yoke pan pivots at (±30, 0). There is a 12.6 x 23.0 mm through-pocket for the SG90 pan servo, plus slotted tab holes for its M2x8 screws and nuts. Underneath, 25 mm corner legs and 3 x 6 mm ribs keep the servo body and the M3 screw heads and nuts off the table. The part prints top-face-down with no supports.
