Micro Servo And Horn Sorting Caddy
A 137 x 70 x 18 mm drawer caddy for spare servos. It has ten 25 x 14 mm upright pockets, 16.4 mm deep, sized for 9 g micro servos (SG90 / MG90S class, body about 23 x 12.5 mm): each servo stands with its mounting tabs on the rim and its lead hanging over the edge. Along the front are three 43 x 32 mm scooped bins for loose horns, horn screws and spline adapters.
Tilt Servo Side Upright
A 70 x 90 x 6 mm side upright for a tilt axis. It holds a standard MG996R-size servo in a 41.5 x 20.5 mm body window, with M4 tab slots on each side, and has a gusseted foot flange that takes two M3 screws (3.4 mm holes) to fix it to a chassis or pan platform. It prints flat with the inner face up, so the servo load runs along the layers instead of across them.
Knee-Driven Lower Leg With Foot
A 145 mm lower-leg shank and foot for a small servo-driven walker. The knee hub bolts to a round servo horn using radial M3 slots that fit a range of horn patterns, and it has a 9 mm spline-clearance hole. A 625 bearing (5 x 16 x 5 mm) presses into the upper boss, and an M5 bolt runs through it as the outboard pivot, so the servo shaft doesn't take the side load. The shank is a flanged, tapered I-beam and the stadium foot is hollowed to save weight.
Hip-Driven Shoulder Clevis
A U-shaped shoulder clevis for robot arms. The 60 x 86 x 5 mm base plate bolts to a hip servo horn through a 9 mm centre hole and four radial M3 slots (r 7–15 mm). The two 6 mm cheeks rise 75 mm: one has a 20.6 x 41.3 mm MG996R-size pocket with tab slots, and the other has a 5.5 x 16 mm vertical M5 slot for the idler pivot, so you can line the pivot up with the servo shaft.
Horn-And-Bearing Joint Yoke
A C-shaped yoke for a robot arm joint. The top arm bolts to a servo horn (7 mm centre hole plus two 2.4 mm screw slots) and the bottom arm holds a 624 bearing (13 mm OD) press-fit on the same axis, so the servo is supported on both sides instead of hanging off its spline. The 5 mm back plate has four M3 clearance holes on a 16 x 20 mm pattern to mount the next arm link, and the part prints on its side so the joint loads run along the layers, not across them.
Horn-Side Drive Arm
A 5 mm thick, 98 mm long drive arm that bolts onto a hobby servo horn. A 2.4 mm radial slot running 6–22 mm from the pivot takes M2 horn screws at any horn hole spacing, and a 7 mm access hole sits over the spline screw. The far end has a pad with two M3 self-tap pilots (2.6 mm, 15 mm deep, 12 mm apart) that screw into the pad edge, so you can attach a linkage, gripper finger or flag.
SG90 Twin-Groove Tendon Spool
A two-groove tendon spool that screws onto an SG90/MG90S servo horn. It pulls a flexor line in one groove and lets out an extensor line in the other, so one servo drives a tendon finger both ways. It is 37 mm across and 22 mm tall, with 16 mm drums, a Ø7.5 mm bore so a screwdriver reaches the horn screw, a Ø9 mm recess for the horn hub, M2 clearance holes at radii of 12 and 15 mm on four arms, and Ø1.6 mm tie-off holes.
SG90 Tilt Servo Tower
An upright tower that holds an SG90 micro servo on its side as the tilt axis of a pan-tilt head. It has a 23 x 12.6 mm through-window for the servo body, slotted tab holes so the tab screws still fit if the spacing varies a little, and a 44 mm tall wall braced by two gussets. The foot has three M3 clearance holes (3.4 mm) for bolting it to a pan plate or chassis deck.
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.
Print-In-Place Geared Claw Gripper
A print-in-place two-jaw claw whose jaws carry 16-tooth spur gears that mesh directly, so a single servo pushrod on the M2 lever drives both jaws symmetrically — no pivot screws, no assembly, 0.4 mm clearance on every mating face. Overall 74 x 86 x 9 mm; jaws swing from a 13 mm closed grip to about 45 mm open, and the 70 x 16 mm rear plate mounts on two M3 clearance holes at 50 mm spacing.
