Is this real CAD or just a mesh?

Real CAD. Parts are built on a professional boundary representation kernel, not a frozen mesh, so dimensions are exact and every feature stays editable.

STEP for CAD work, STL and 3MF for your slicer, and GLB for the web. Before you export, the builder checks the geometry for open edges, thin walls and risky overhangs, and tells you what it finds.

Do I need an account to try it?

No. You can generate your first part without signing up, then keep it by creating an account.

Can I change the part after it is generated?

Yes. Every dimension is a named parameter with a slider. Adjusting one re-runs the geometry kernel directly, with no AI call and no cost.

What if the part does not build?

The system repairs most failures automatically before you see them. When it cannot, it tells you why rather than returning a broken file.

Makers and engineers who need a part that fits something real: an enclosure, a bracket, a replacement, an adapter. It is not a tool for generating decorative models.

Real geometry

Not a mesh blob. A part.

Every feature is driven by a named parameter you can still edit after generation. Change a wall thickness and the geometry rebuilds exactly, with no remodelling. It is built on a boundary representation kernel, not a frozen mesh.

How it works

Idea to object.

Three steps, and the first one is a sentence.

Describe it

Type what you need in plain words, or attach a photo of the thing it has to fit.

Tune it

Every dimension is a slider. Adjust and the part rebuilds instantly, with no AI call.

Make it

Export STEP for CAD, STL or 3MF for your slicer, GLB for the web. The builder checks printability first.

Parametric control

Every dimension is a slider.

Generation gives you a starting point. The sliders are how you make it yours, and they re-run the real geometry kernel rather than approximating. Sliders are free on every plan.

The Fit Machine

Fits what you already own.

Tell it the thing your part has to mate with and it builds around the real dimensions, so the first print fits instead of the third.

The difference

Mesh toys versus real parts.

Most AI 3D tools generate a mesh you cannot dimension, cannot edit, and cannot hand to a machine shop.
