Features

Pick a place you care about. Shape it on the map, decide what belongs in the model, inspect the finished geometry, then send a slicer-ready 3MF straight to your printer workflow.

No account, no render queue, no paid controls hiding behind the preview. This page covers the public workflow from the first selection to the final source and license review.

Start with a rectangle, square, circle, editable freeform polygon, preset shape, imported SVG outline, or a single letter. Move it, resize it, rotate it, lock its proportions, or switch it into Project Mode without drawing the area again.
Shape the model around the place

Pick the right kind of model

City detail, multi-plate projects, wide terrain, and planetary relief all start from the same map workflow.

Build the city that is actually there

Generate up to 50 km² of terrain, buildings, roads, rail, paths, water, parks, beaches, runways, raceways, and other mapped detail when the source data has it.

Turn one area into a multi-plate project

Split an Earth City selection up to 500 km² into as many as 20 pieces, each no larger than 25 km². Use strips, grids, clipped hexes, or puzzle cuts, keep one physical scale across every piece, and download the finished set as a ZIP.

Go wide with Terrain tile

Cover any valid Earth footprint with terrain relief, water, surface colors, terrain paint, contours, and imported GPX routes. Terrain grid density and source resolution adapt to the footprint and browser memory. City buildings and mapped transport stay out, so the model spends its detail budget on the landscape.

Print Earth, the Moon, Mars, Mercury, Venus, Ceres, or Vesta

Use Earth map and elevation data for cities and terrain, or switch to a terrain-only planetary workflow. Browse named planetary landmarks and place printable markers where the selected body supports them.

These are real Mini Skyline previews and exports, made with the same tools listed on this page.

Import one or more GPX tracks or routes, then set the printed width, height, and color. Use them in City, Project, or Terrain tile models, with the line following the terrain it actually crossed.

Choose Natural or Rows placement, detailed V2 or lightweight Micro trees, eligible terrain, density, and scale. Add foliage or rock scatter where supported while collision rules keep props away from water, buildings, roads, walls, edges, and each other.

The full feature set

Use the sections below for the whole list. Mode-specific tools stay out of the way when the selected model cannot use them.

Shape it and add your own detail

Shape the model around the place

Start with a rectangle, square, circle, editable freeform polygon, preset shape, imported SVG outline, or a single letter. Move it, resize it, rotate it, lock its proportions, or switch it into Project Mode without drawing the area again.

Add what the map missed

Draw custom buildings, roads, paths, fences, Map Text, and other linework directly on the selected area. Edit vertices, set real model-space widths and heights, reorder overlaps, duplicate parts, and keep every edit in the browser.

Paint the ground you want

Replace imported terrain or water classifications with a circular or square brush or an editable polygon. Paint stays local to the browser, and Project Mode clips the same operation cleanly across piece boundaries.

Put a real route on the model

Import one or more GPX tracks or routes, then set the printed width, height, and color. Use them in City, Project, or Terrain tile models, with the line following the terrain it actually crossed.

Finish the edge on purpose

Add an inward or outward frame to a rectangular model, choose its profile, width, height, and colors, then put raised or recessed text on any side. Letter and SVG selections keep their own shaped boundary.

Build the mapped place

Keep buildings grounded

Use mapped heights when they exist, choose how unknown heights behave, scale or cap tall buildings, filter unwanted footprints, and add terrain-following foundations. Draw a missing building yourself when the source map leaves it out.

Control mapped layers, water, and bridges separately

Turn roads, paths, rail, runways, raceways, parking, parks, forests, beaches, golf, and the wider land-type catalog on or off. Print water in the model, treat it as land, cut it out, or make separate inserts, while explicitly mapped bridges stay raised across it.

Give the relief readable contour lines

Add minor and index contours that follow the source elevation. Choose automatic or exact spacing, metric or imperial units, line width, raised height, color, simplification, and index frequency.

Build forests instead of green dots

Choose Natural or Rows placement, detailed V2 or lightweight Micro trees, eligible terrain, density, and scale. Add foliage or rock scatter where supported while collision rules keep props away from water, buildings, roads, walls, edges, and each other.

Tune it before you print

Size the model for the printer you own

Set exact physical dimensions or a shared map scale, tune base thickness and relief strength, and widen small features around the nozzle and line width you plan to use. One-color output is there when material separation is not the goal.

Use the preview as an editor

Inspect the finished mesh before download. Recolor it without regenerating, then open the 3D editor to move or rescale buildings, redraw roads, sculpt terrain, place or clear trees, and paint materials before one Apply rebuilds the model.

Save the work, not only the export

Download a workspace with the selection, settings, GPX routes, custom content, paint, text, and Project Mode setup. Reopen it later, recover the latest local autosave, color terrain by feature or elevation, or save and load a palette without touching the geometry.

Take it to the slicer

Build it in your own browser

Static providers prepare compact source bundles, then browser workers build the preview and write the 3MF on your device. There is no account, render queue, or restorable cloud model.

Send named, printable parts to the slicer

Export a geometry-preserving core 3MF with named semantic parts and display colors. Terrain, bases, water, side walls, foundations, and mapped detail are built as printable solids for AMS or MMU workflows, manual swaps, one-color printing, or your own slicer remapping.

Know what went into this exact model

Each export carries the source and attribution metadata for that run. The export review names the providers, commercial-use status, public-sharing status, required conditions, and unresolved sources before you download.

Keep the workflow local and reusable

Selections, custom geometry, paint, text, and saved projects stay in your browser or in files you download. Mini Skyline prepares source data for the model without turning your work into a hosted project that you have to recover from an account.

Start with somewhere you know

A street you grew up on, a trail you finished, a stadium, a mountain, or a crater all begin the same way. Put the place on the map and shape the print around it.
