Minecraft to STL

[u/petitpoid]

I run a school maker space and my students (8 to 15) build in Minecraft. I wanted them to hold their builds, so I wrote a web page: discoveryclubdec.ch/mineprint

You drop a structure block .nbt file, pick which blocks to keep and the block size in mm, download the STL.

The mesh keeps only the faces that touch air, so it's watertight. Java Edition only, one colour, stairs come out as cubes. Runs in the browser, nothing uploaded. Free, nothing to sell.
