Short

61 words

Jarvizar City Model turns any place on the map into a multicolor 3D printable model with terrain, water, parks, roads, and buildings. Where a public LiDAR survey covers the area, it rebuilds the real roofs, towers, and spires from the scan. The app runs in the browser with no account and exports Bambu Studio and PrusaSlicer projects, 3MF, and STL files.

Jarvizar City Model is a web app for making 3D printable models of real places: cities, hometowns, mountains, islands, stadiums, and racetracks. People pick an area on the map, set the size and colors, and the app builds the model in the browser from OpenStreetMap and Overture Maps data and public elevation data. Terrain, water, parks, roads, and buildings each print as their own part in their own filament, and the files open in Bambu Studio and PrusaSlicer with the colors already assigned.

Where a public LiDAR survey covers the area, the app downloads the scan straight from its publisher and measures the real shapes of roofs, towers, and spires. LiDAR only models are built from the scan alone, with the buildings, trees, and bridges in it. Coverage includes most of the United States, much of Europe, New Zealand, parts of Canada, and cities such as Tokyo and São Paulo, from over 50 sources.

The app is free, including downloads up to 256 mm across. Paid tiers add custom routes, names and map pins, prints split across several plates, LiDAR outside the free areas, and LiDAR only models. They are sold as lifetime access through a MakerWorld crowdfunding campaign from November 10 to December 10, 2026. Adam Jarvis built the app after making over 150 map miniatures by hand for MakerWorld as Jarvizar.

What It Does

  • Any place on the map, found by search or by dragging a box, cut as a rectangle, rounded rectangle, circle, or hexagon.
  • Terrain, water, parks, roads, and buildings as separate parts, each in its own filament. Bridges and trees are optional.
  • 16 color themes, any filament color for any part, and separate colors for tall buildings, road types, and terrain height bands.
  • LiDAR buildings, with roof shapes measured from public laser scans, and LiDAR only models built from the scan alone.
  • Routes from GPX, FIT, TCX, KML, KMZ, or GeoJSON files, printed along the streets in their own color, and over 125 built-in racetracks.
  • Names and map pins printed on the model.
  • Large models split across as many plates as needed, each sized to the printer's bed.
  • An editor for removing or raising buildings, widening roads, and drawing roads, buildings, and land cover before downloading.
  • Single-color printing works too: streets, water, and buildings sit at different heights, so they still show.
  • Models are built in the browser. Nothing is installed or uploaded.

From the campaign page, in Adam's words:

I've been making miniature cities & racetracks for MakerWorld for a couple of years now. By now I've created over 150 of them, all by hand in Blender using the Blosm add-on. Over time, those models have been downloaded more than 130,000 times, and nearly 28,000 people have followed along on MakerWorld!

Every one started as a very basic model that required a lot of cleanup before it would actually print. Zero-height roads disappearing in the slicer, non-manifold edges, splitting everything into separate parts so it could be printed in multi-color, spending hours manually fixing incorrect heights and adding back missing buildings, etc.

Over time, I also started getting more and more requests for places I hadn't made, many of which I'd never even considered myself. The existing online tools were great starting points, but I kept wishing there was an easier way for anyone to go from map data to a finished, printable model.

That's what led me to start building City Model. Making all those miniatures by hand taught me a lot about what makes a map model look good and print well, and I wanted to put that experience into a tool that anyone could use to make their own.

I'm a software engineer by day, so building the web app itself was the more familiar part. LiDAR was by far the biggest challenge. Every country, and sometimes even individual states or cities, publishes its scans differently. Getting all those different sources working together, and keeping them working, has taken a lot of time.
