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.*

Project kits

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.
