    03 · The Designer

    A real 3D editor, with an AI that builds on the same canvas.

    Drag in shapes, cut holes, bring in your own STL — or describe the part and let the AI draft it. It edits the exact model you're looking at, every change is priced as you go, and what you see is what we print.

    Shapes

    11 parametric primitives

    Box, cylinder, cone, sphere, torus, tube, wedge, pyramid, hex prism, rounded box — and text, raised or cut.

    Booleans

    Holes & groups

    Flip any shape to a hole and group it — it cuts straight through whatever it's grouped with.

    Precision

    Exact sizes, snap & align

    Move, rotate and scale with 1 mm / 15° snapping, align and mirror, undo and redo. Millimetres or inches.
