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.
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.
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 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.
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.
