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 Self-Balancing Robot Frame
A three-deck, two-wheel self-balancing robot frame for a pair of NEMA17 steppers, with 90 mm set-screw wheels, tip-over skids and a top-mounted 18650 battery tray.
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.
NEMA17 Geared Radar Scan Turret
A stepper-driven pan turret: 3:1 printed gears turn a head that spins on two 608 bearings, with a lockable tilt cradle and an M3 grid face for an ultrasonic sensor, ToF sensor or camera.
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.
N20 4WD Skid-Steer Rover Base
A printed 4WD skid-steer rover for four N20 gearmotors, with a 2S 18650 cradle, a raised Raspberry Pi 4 deck and a front bumper with a sensor grid.
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 Twin-Motor Strandbeest Walker
A four-legged Theo Jansen walker at 2x scale. Each side has its own NEMA17, so it steers like a tank. It uses M4 pivots and a numbered layer stack so the separately printed links line up.
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.
SG90 Tendon-Driven Robot Hand
A five-finger robot hand driven by five SG90 servos. Twin-groove spools pull nylon tendons in both directions, so every finger actively curls and straightens.
NEMA17 Belt-Drive SCARA Drawing Arm
A 260 mm reach desktop SCARA arm: two NEMA17s drive the shoulder and elbow through 3:1 GT2 belts on 608 bearings, and an SG90 lifts the pen.
N20 Twin-Track Mini Tank Chassis
A skid-steer mini tank with print-in-place 12 mm-pitch tracks built to match its 12-tooth sprockets. Two N20 gearmotors drive it and a 2x18650 deck powers it.
NEMA17 Rocker-Bogie Mars Rover Chassis
A six-wheel rocker-bogie rover chassis with a NEMA17 driving each wheel directly, 608-bearing pivots and a differential bar that keeps the deck level over rough ground.
SG90 Mini Delta Pick-and-Place Robot
A three-servo desktop delta robot. Three SG90 arms drive a parallelogram-linked effector over a 150 mm tall frame, using split printed ball joints held together by springs.
SG90 Sawtooth-Foot Inchworm Crawler
A one-servo inchworm robot. An SG90 flexes a two-segment body, and sawtooth feet that grip in only one direction turn the rocking into steady forward crawling.
