Mini Skyline · public beta · one developer
Free to use, free to sell what you print*, and nobody asks who you are.
Draw a box on the map. Everything inside it — buildings, streets, water, terrain, trees — becomes a printable model, built by workers in your own browser while you watch. No account, no ads, no paid tier, no export limit. Then you print it, and the print is yours.
four colors · 160 mm · built in a browser tab
Free, and not the trial kind
Every feature is open to everyone. No sign-up, no email, no ads, no watermark, no export cap, nothing stored on a server. Sell the prints you make: every run records the exact commercial-use decision for the data it used. Sources · Privacy · Selling a print
Surfaces you can print
Buildings, roads, paths, rail and runways, rivers and coastline, parks and green space, beaches, bridges, and terrain relief with printable contour steps. Multi-plate projects whose pieces share one physical scale — and four other worlds: the Moon, Mars, Mercury and Vesta.
Scatter built by hand
Fifteen tree species modeled for this app — alpine pine, boreal spruce, desert palm, olive, acacia, cypress, bamboo — plus a micro set for small scales and ground scatter of foliage and rocks. Placed by climate and density, kept off walls and out of water.
Textures on any surface
Paint a material onto any surface you can see — terrain, water, roofs, roadway. Give every layer its own color, or drop in a four-color preset built for a four-slot printer. Palettes save and reload on their own.
Bring your own lines
Drop a GPX track on the map and print the route across the terrain it actually crossed. Draw your own roads, paths and fences at a real width in millimeters, add buildings that were never mapped, and raise text and frames off the base.
A real editor, not a slider
Open the finished model in a full 3D editor: move and rescale buildings, redraw roads, sculpt terrain by hand, plant or clear trees, paint materials. Everything stays live until one Apply rebuilds the mesh.
What you can control
Rectangular, circular or freeform footprints. Physical size from the default 160 mm, map scale, base thickness and relief strength. Every layer separately: roads, water, trees, terrain paint.
What you get out
One slicer-ready core 3MF, written in your own browser tab — no render queue, no account, nothing uploaded. It carries named parts, display colors, source attribution and the exact commercial-use decision for that run.
* Commercial use is determined by the underlying map data your run pulled in, not by Mini Skyline. Most areas come out commercially viable, but please verify against the attribution file bundled inside your export — it names every source used and the licence decision for that run. Selling a print
