Minecraft – copy part of a Minecraft multi-player (SMP) map to a single-player map

minecraft-java-edition

Is it possible to somehow get the map from an SMP server as a mere player? I did some large Redstone circuitry, and I would like to copy it into my SSP map.

If not, can I extract the loaded chunks from memory?

You can use World Downloader.

Press Esc in-game and press L to start downloading. It will download everything you see — about 160 blocks away from you, from bedrock to the sky limit. To stop the download, press L again.

Then, just look in your single-player maps.
