Design a custom 3D-printable part for your home in one chat

You get a 3D design tool with sliders for size and style, then download a print-ready file without learning any CAD.

About 20 minutes A few steps

Can AI design a replacement part I can 3D print?

Yes. Give Gemini your measurements and ask Canvas to build a 3D design tool that exports an STL file. As of October 2026, Google showed this with Gemini 4 Argon, which needs a Google AI Pro or Ultra plan. If you own a 3D printer, print the file at home. If you don't, send the STL to a local or online print service. For parts that carry weight, double-check the measurements before you print.

The prompt that gets copied

Build me an interactive 3D design tool for a [PART TYPE, e.g. replacement furniture leg] for my [FURNITURE ITEM, e.g. low wooden sofa]. Rough measurements: [ROUGH MEASUREMENTS, e.g. 4 in tall, 8 mm screw hole]. Show the part in 3D so I can spin it around. Give me sliders for height, width and thickness, and three style options such as plain, rounded and stacked spheres. Keep any screw holes or fit points at the sizes I gave you. Add a button to export the current design as an STL file ready for 3D printing, and a short note on which print material and settings suit a part that has to carry weight.

Describe the part you need, like a shelf bracket or furniture foot, with rough measurements. Gemini builds a 3D design tool with sliders and exports a file a 3D printer can use.

Step by step

  1. Measure the spot where the part goes
  2. Open Gemini, pick Canvas and paste the prompt with your measurements
  3. Use the sliders to try styles and sizes in the 3D preview
  4. Export the STL file and print it at home or send it to a print service

What you'll get

A 3D design tool in your chat with live sliders and style choices, plus a downloadable STL file for printing.
