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 Belt-Drive Camera Slider
A motorized camera slider on twin 8 mm rods. A NEMA17 drives a GT2 belt, and a four-LM8UU carriage carries the camera for smooth time-lapse and video moves.
NEMA17 Leadscrew Push-Pull Actuator
A compact linear actuator for props and animatronics. A NEMA17 turns a T8 leadscrew, and a carriage on twin 8 mm rods pushes and pulls through a clevis with about 120 mm of travel.
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.
NEMA17 Cantilever Pen Plotter
A GRBL pen plotter: two NEMA17s drive a cantilevered X arm on 8 mm rods and LM8UU bearings, with a guided, SG90-driven pen lift. Draws up to 240 x 260 mm.
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.
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.
SG90 Ackermann Steering Rover Chassis
A car-style rover with real Ackermann geometry: one SG90 steers the front knuckles through a trapezoid tie bar, and two N20 gearmotors drive the rear wheels.
N20 Self-Locking Worm-Drive Winch
A compact N20-powered hoist with a printed 24:1 worm drive that holds its load when the power is cut. The drum runs on twin 608 bearings, with a fairlead brace on top.
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 Tendon-Driven Continuum Trunk Arm
A soft-robotics "elephant trunk": eight rolling-dome vertebrae on a PTFE backbone, bent in any direction by three SG90 servos pulling tendons through Bowden guides.
