Desktop app

Broken part. Plain English. New STL.

Figure is a desktop app for designing printable parts. Describe what you need, tweak the sliders, export the STL. The geometry is generated locally — OpenSCAD runs underneath.

How it works

From a description to a printed part, in three motions.

No CAD to learn. No code to read. The workflow is the conversation; the geometry follows.

Step 01

Describe what broke.

Type it, upload a photo, or drag in an STL. Plain English works — measurements help.

Step 02

The geometry takes shape.

The model builds from your description. Nudge it with sliders — no CAD, no commands, no code.

Step 03

Export and print.

Hit Export STL. Slice it in your usual tool. Print, fit-check, adjust if needed.

From the wild

Parts people actually printed.

Real outputs from the app. The first started as a photo of the broken original; the second, a paragraph of description.

Example 01 — From a photo

A replacement fan knob.

Reconstructed from a photo of the broken original. Measured with calipers, fit-tested on the third try.

"The oval bore (5.25 × 6.25 mm + 0.2 mm tolerance) runs through the entire piece to grip the splined shaft."

A 3D rendering of a knurled volume knob inside the Figure app in dark mode, with sliders for diameter, height, shaft, D-flat depth, and knurl count.
Example 02 — From a description

A stereo volume knob.

Built from one paragraph of description. Knurled grip, flat top, D-shaped bore — generated, then tuned to the shaft.

"A round plastic knob, about 35 mm wide and 20 mm tall, with a D-shaped hole from the bottom to center for a shaft. Make it look nice — flat top, knurled around the circumference."
Works with your setup

Your model, your key, your machine.

Figure connects to the model provider you already pay for. Geometry is generated locally with OpenSCAD. Nothing is rendered in a cloud you don't control.

  • Bring your own API key. Stored securely on your device. Never sent to us — we don't run a server.
  • OpenSCAD runs locally. The geometry engine ships inside the app. Your descriptions and STLs stay on your machine.
  • No subscription. No account. Free to use. You pay your model provider for tokens; that's it.
