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.
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 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.
NEMA17 Geneva Indexing Turntable
A NEMA17 stepper drives a 6-slot Geneva wheel that turns a 140 mm platter in exact 60° steps and locks it firmly between moves. Runs on two 608 bearings on a fixed 8 mm rod.
SG90 Parallelogram-Leg Biped Walker
A 4-servo biped whose parallelogram legs keep the ankles level. It leans with ankle-roll servos and steps with hip-pitch servos, so walking takes 4 SG90s instead of 12.
MG90S Six-Servo Stewart Platform
A desktop 6-DOF Stewart motion base. Six MG90S servos drive print-in-place ball-joint pushrods to tilt, twist and lift a payload deck, and a Pi Zero rides on the deck underneath.
