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.

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.
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.
SG90 Scotch-Yoke Flapping Wing Rig
A single SG90 servo drives a Scotch-yoke slider on a 624 roller that flaps two bolt-on bat wings in sync, about ±37°. Build it into a dragon, bat or bird.
