Mini Skyline · public beta · one developer

A map-to-3MF tool, still being built in the open.

Draw a box on the map. Everything inside it — buildings, streets, water, terrain — becomes a printable model, generated by workers in your own browser while you watch. Then you print it.

What you can build

Dense city tiles with buildings, streets, water and greenery. Multi-plate projects whose pieces share one physical scale. Wide terrain relief with printable contours. And four other worlds — the Moon, Mars, Mercury and Vesta.

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. Frames, raised text, colors, and your own drawn roads, buildings and GPX routes.

What you get out

One slicer-ready core 3MF, built by workers in your own browser — no render queue, no account, nothing stored. It carries named parts, display colors, source attribution and, since V1.60, the exact commercial-use decision for that run. Sources · Privacy · Selling a print
