Open a Minecraft: Java Edition world save in your browser, select an area by block coordinates, group its blocks into filament colors, and export a printable 3MF. The world never leaves your computer.
How it works
Choose the world folder or a ZIP of it, pick the area on the block map, set the height range, and generate a preview. The Colour Board groups every block in the selection into 1 to 16 filament slots, and the export writes one printable part per filament.
What it supports
Vanilla Minecraft: Java Edition worlds from version 1.18 onward, Overworld only. Each import reads an area of up to 1,280 by 1,280 blocks. Bedrock worlds, .mcworld files, and modded worlds are not supported.
Made for printing
Large selections can be planned as tiles that fit your printer’s build volume, and trees that print better upside down can move to their own plate with a peg and socket for gluing.
Local by design
World files are read in the browser. Nothing is uploaded to prepare the model or write the export, and the original save is never changed.
Common questions
Does it work with Bedrock Edition?
Not yet. The importer reads vanilla Minecraft: Java Edition worlds from version 1.18 onward. Bedrock worlds, .mcworld files, and modded worlds are not supported.
How large an area can I print?
Each import reads up to 1,280 by 1,280 blocks around the player, the world spawn, or coordinates you enter. Within that area you choose the exact footprint and height range, and large selections can be split into tiles that fit your printer.
Is my world uploaded anywhere?
No. The world is read in your browser, the model is prepared on your device, and the 3MF is written locally. The original save is not modified.
Can I print it in a single color?
Yes. Choose one filament slot and the build exports as a single color. Up to 16 slots are available for multicolor printers.
Can I get an STL?
The export is a 3MF, which every current slicer opens. If another tool needs an STL, open the 3MF in your slicer and export it as STL there; the filament colors do not survive that conversion.
Is it free?
Yes. Like the rest of Mini Skyline, the Minecraft importer needs no account and no payment.
