The full story
A teacher running a free digital club for 8 to 15 year olds in Switzerland wanted the children to hold their Minecraft builds in their hands. Claude Code wrote a browser tool that parses Minecraft save files and makes a printable mesh.
According to the post, Claude checked real save files before coding and caught a format change the documentation did not mention. It verified the mesh with an independent Python rewrite giving the same 716 triangles byte for byte. Everything runs client side with no libraries, and eight prints had been made in class so far.
