McTo3D
McTo3D exports a selected region of a Minecraft world as an STL file that can be sent to a 3D printer.
What it does
A player marks an area with a Golden Hoe, left-clicking one corner and right-clicking the opposite corner, or sets the bounds with commands based on coordinates or the player's position. The selection can then be stretched vertically with the expand command, which adds blocks above or below the chosen region. The result is written out as an STL model.
Two export modes are available. Raw mode exports bare geometry only, a format that fits single-color prints or touch-ups made afterward in Blender. Color mode keeps color data, and the output is meant for multi-material printers such as Bambu Lab AMS or Prusa MMU setups. The files are formatted for common slicers including Bambu Studio, Cura and PrusaSlicer, and the author notes that the structure should be checked for integrity in the slicer before printing.
The mod runs on the client only, so players install it alone and servers do not need it. It requires Fabric and is built for the 1.21.10 release. The mod is released under All rights reserved and is not open source, and the author's public link is a wiki.
