Pan Servo Base Housing
This is the base of the 'MG996R Heavy Pan-Tilt Camera Gimbal' kit. It is an open-bottom box, 100 x 100 x 48 mm, with a 41.5 x 20.5 mm window in a 4 mm deck. One MG996R pan servo drops into the window and hangs by its tabs, held with M4 screws through four 4.5 mm slots. The deck also has six 4.0 mm M3 heat-set bores for three 624 roller thrust forks on r = 42 mm, and four 4.5 mm M4 bench-screw holes run through full-height corner columns. It prints deck-down with no supports.
MG90S Radial Servo Cradle
One of six MG90S servo cradles for the 'MG90S Six-Servo Stewart Platform' kit. It is an L-bracket with a 44 x 20 x 5 mm foot, and two counterbored M3 clearance holes 32 mm apart bolt it to the base plate's heat-set inserts with M3x10 screws. A 4 mm wall with a 23.3 x 12.7 mm window holds the MG90S so its shaft points radially outward, 22 mm above the base. The tab-screw slots take M2 self-tappers at tab spacings from 26 to 30 mm, and two gussets carry servo torque into the foot.
Trunk Servo Base Deck
This is the foundation of the 'SG90 Tendon-Driven Continuum Trunk Arm' kit. It is a Ø140 mm deck, 3.5 mm thick, with a 32 mm skirt that has a 2 mm wall. It holds three SG90 micro servos in 22.8 x 12.4 mm through-pockets on a 52 mm radius. Each pocket has 2.4 mm M2 tab slots that cover 26–30 mm tab spacing. The trunk tower bolts to the deck with 4x M3 through 3.4 mm holes on a 36 mm radius, with captured 5.7 mm hex nut pockets under the deck. The deck also has a Ø44 wire pass-through, three 3.4 mm radial slots (R46–R60) for the Bowden guide blocks, six lightening windows and three 16 x 10 mm cable notches in the skirt. It prints upside down with no supports, and the hole pattern is mirror-symmetric, so it reads the same either way up.
Ankle Roll Servo Block
This is the ankle block for the 'SG90 Parallelogram-Leg Biped Walker' kit, 44 x 24 x 58 mm. An SG90 ankle-roll servo sits upright in a 23.6 x 12.8 mm front-wall window, held by two M2x10 screws and nuts through tab slots. A 6 mm lug on top has two 3.4 mm pivot holes 32.0 mm apart for the leg links, fastened with M3x20 screws and nyloc nuts. Prints upright with no supports, and one design fits both legs.
Biped Hip Servo Torso
An 80 x 70 x 32 mm open torso frame for a small biped robot. Both side walls have a 23.6 x 12.8 mm window with tab slots for a micro-servo (SG90 size) to drive each hip. Each side wall also has an M3 pivot hole for a follower link. The top deck has four 4.0 mm bores for M3 heat-set inserts, and the base plate has a lightening cutout to save weight.
Upper Leg Servo Plate
The inner half of the upper leg in the 'MG996R 12-DOF Quadruped Robot Dog' kit. It is a 169 x 60 x 5 mm plate. At the shoulder it takes a 25T round servo horn: a 9 mm centre hole and four 3.4 mm radial slots at r 7–15 mm for M3x10 screws. At the knee it holds a second MG996R in a 41.3 x 20.6 mm pocket, with tab slots that fit 46–55 mm hole spacing for M3x16 screws. Four 10 mm x 44 mm posts with 4 mm bores for M3 heat-set inserts join it to the outer bearing plate.
Twin Hip Servo Frame
The front and rear end plate for the 'MG996R 12-DOF Quadruped Robot Dog' kit. You print the same part twice. Each 170 x 66 x 6 mm plate holds two MG996R hip servos in 41.3 x 20.6 mm pockets. Four slots per pocket take M3x16 screws with nuts and fit tab hole spacings from 46 to 55 mm. A 30 mm rear ledge takes two 2020 rails at 60 mm centres on M5x10 screws and T-nuts. The plate also has a 30 x 16 mm wire pass-through and lightening windows.
Micro Servo Slot Mount Plate
A 64 x 22 x 5 mm slotted servo carrier used at all four axes of the 'MG90S Animatronic Desk Lamp Robot' kit. It takes an MG90S or SG90 servo through a 22.8 x 12.6 mm window, with M2 screws through the tabs on a 27.8 mm pitch. Two rounded 3.4 mm M3 slots allow ±3 mm of travel on the kit's 44 mm heat-set insert pitch, so you can line up the spline on the joint axis even when a clone servo's tabs are a little off.
Weighted Yaw Base Tub
The foundation of the 'MG90S Animatronic Desk Lamp Robot' kit. It is a round tub, 120 mm OD x 40 mm tall, and the turntable skirt centres on a built-in thrust rim: a flat annulus from r=54 to r=60 at Z=40 with a 45° chamfered ledge underneath. Two 10 mm posts hold the slotted micro-servo plate on M3 heat-set inserts, so an MG90S or SG90 yaw servo hangs in a clear bay. A ring trough at r=41–57 holds steel washers or BBs as ballast, and a 14 x 10 mm notch lets the cable out.
Servo Tab Clamp Frame
A 36 x 34 x 6 mm black clamp frame from the 'SG90 Wheeled Serpentine Snake Robot' kit. It holds an SG90 or MG90S servo's mounting tabs down onto the Servo Segment Housing's z=33 seat, and the servo body and output shaft pass through its 23.6 x 13.0 mm opening. Four 3.4 mm holes on a 16 x 22 mm pattern take M3x12 SHCS into the housing's heat-set inserts. The frame clamps the tabs flat, so it works whatever the clone's tab thickness or hole spacing.
Servo Segment Housing
Open-top body segment for the 'SG90 Wheeled Serpentine Snake Robot' kit. It measures 50 x 36 x 33 mm and holds an SG90 or MG90S servo on a z=33 tab seat. Four M3 heat-set pillars take the clamp frame, and a 16 x 20 mm M3 heat-set face bolts to the next yoke. It also has an M4 pivot slot for the 624-bearing joint bolt and two M3 heat-set floor bosses for the wheel axle bridge.
SG90 Delta Servo Cradle
An L-bracket SG90 servo cradle for the 'SG90 Mini Delta Pick-and-Place Robot' kit; print three. It has a 44 × 35 × 5 mm pad and a 24 mm tall wall with a 23.6 × 12.8 mm window for the SG90's 23 × 12.2 mm body. The tab slots take M2 screws and nuts, and two gussets carry the arm torque. The pad hangs from the top plate on M3x10 SHCS into captured M3 nuts, with ±4 mm of radial adjustment.
Five-Servo Forearm Deck
A 150 x 166 mm ribbed forearm deck that holds five SG90-class micro servos side by side at 36 mm pitch to drive the tendons of a five-finger robot hand. It has 23.4 x 12.6 mm servo pockets with open ear slots that accept a range of M2 tab-screw spacings, M3 clearance holes (3.4 mm) for a tendon comb and wrist mount, a 32 mm skirt with a 2 mm wall, and a cable notch.
Hexapod Chassis Base Plate
The main body of the 'SG90 18-DOF Hexapod Walker' kit: a 164 x 124 x 4 mm plate with 30 mm corner chamfers and six SG90/MG90S hip-servo pockets (23.4 x 12.8 mm). Each pocket has slotted M2 tab slots that take tab hole spacings from 26 to 31.6 mm, so one plate fits most micro servos. It also has four 3.4 mm M3 standoff holes at (±20, ±30) for M3x30 standoffs to the deck, a 24 x 40 mm central wiring pass-through, and front and rear cable slots. It uses about 61 cm³ of material.
SG90 Side-Shaft Servo Cradle
This L-shaped cradle is part of the 'SG90 3-DOF Ball-Balancing Platform' kit (print ×3). It holds one SG90 micro servo with its shaft horizontal. The servo body goes through a 12.4 x 22.8 mm window in a 5 mm wall, and the tabs rest flat against the wall's outer face, with 2.4 mm slots for the M2 tab screws. The 32 x 40 x 5 mm foot bolts to the Tri-Spoke Servo Base Plate with two M3x12 SHCS through 3.4 mm holes spaced 30 mm apart. Two gussets brace the 51 mm wall, and each has a notch so the screw heads can go in from above.
Gripper Servo Palm
This palm is part 6 of the 'SG90 Four-Axis Desktop Robot Arm' kit. It is a 65 x 52 x 5 mm plate that holds the gripper SG90 servo in a 28 x 12.6 mm window with M2 ear slots, which puts the drive-jaw axis at (-10, 0). The M3 idler-jaw pivot runs in a 3.4 mm slot with 5 mm of travel on a raised 2 mm washer pad, so you can set the 20 mm gear mesh. The palm bolts to the forearm tip with two M3 screws through Ø3.4 holes 15 mm apart.
Yaw Turntable Shoulder Yoke
This is the Ø84 x 5 mm yaw turntable for the 'SG90 Four-Axis Desktop Robot Arm' kit. It screws to the yaw servo's double-arm SG90 horn through a 1.8 mm underside pocket with a Ø5.3 centre hole. It also has an upright 5 mm wall with a 28 x 12.6 mm SG90 window and M2 ear slots, which puts the shoulder axis 38 mm above the underside. Two gussets brace the wall, and two Ø9 bosses carry Ø4.0 x 6 mm M3 heat-set bores at (22, ±14) for the 625-bearing idler cheek.
SG90 Arm Base Pedestal
The base and yaw-servo housing of the 'SG90 Four-Axis Desktop Robot Arm' kit. It is a hollow 100 x 100 x 40 mm pedestal with a 5 mm top deck. The deck has a 28 x 12.6 mm SG90 window with 2.4 mm M2 ear slots, which puts the yaw shaft at the deck centre. It screws down with four #8 wood screws through Ø4.8 holes in corner columns on an 84 mm square, and a 14 x 8 mm notch lets the servo cable out.
