Heads up: kits are AI-designed and haven't been test-built. Parts may not fit together or match your hardware as-is — expect to adjust holes, clearances or dimensions. Print one part and dry-fit it before printing the rest or buying hardware.*
Whole builds, not just parts
Each kit is a complete robotics project: every printed part designed to fit together, the screws and electronics you'll need, assembly steps, and a render of the finished machine. Order the whole kit printed in one click, or download every file at once.

NEMA17 Rack-and-Pinion Parallel Gripper
A stepper-driven parallel gripper. One NEMA17 pinion drives two opposed racks, and the jaws slide on 8 mm rods with LM8UU bearings. It opens from 4 to 56 mm and mounts to 2020 extrusion.
SG90 Animatronic Eye Mechanism
A two-servo animatronic eye rig. Two 30 mm eyeballs pan and tilt together on printed gimbal yokes, driven by a pan servo through a scotch yoke and a tilt servo through a slotted paddle.
SG90 Four-Axis Desktop Robot Arm
A 4-axis desktop robot arm that runs on four SG90 servos. It has a turning base, a shoulder carried on a 625 bearing, an elbow and a geared parallel gripper. There are eight printed parts.
SG90 3-DOF Ball-Balancing Platform
A 3-servo parallel platform that tilts and lifts a 150 mm tray. It uses snap-fit printed ball joints and is sized for PID ball-balancing on three SG90s.
NEMA17 Cycloidal Joint Actuator
A stackable 15:1 cycloidal gearbox that bolts onto a NEMA 17. It uses rolling 5 mm steel ring pins and a 625-supported output face, and makes a stiff, low-backlash rotary joint for robot arms.
SG90 18-DOF Hexapod Walker
A six-legged walker with 18 SG90 micro servos, fitted to one set of tolerances: chassis, deck, battery tray and a three-part leg that repeats six times.
