About this Mod
McTo3D - Minecraft to 3D Printing
Turn your Minecraft builds into physical objects.
McTo3D is a utility mod designed to bridge the gap between Minecraft creativity and 3D printing technology. It functions as a simplified CAD tool within the game, allowing players to select, process, and export structures directly into formats compatible with major slicing software (Bambu Studio, Cura, PrusaSlicer).
Whether you are designing architectural models or custom figurines, McTo3D provides a streamlined workflow from block placement to STL generation.
🌟 Key Features
🛠️ Precision Selection Tools
Define your export area with accuracy using two distinct methods:
- Wand Selection: Use the Golden Hoe to quickly define corners (Left-Click for Position 1, Right-Click for Position 2).
- Command Selection: Use
/pos1and/pos2for precise coordinate targeting based on your player position.
📐 Axis Manipulation
Need to capture underground foundations or high rooftops without moving?
- Vertical Expansion: Easily adjust your selection boundaries using the
/expandcommand.- Example:
/expand 10adds 10 blocks upwards. - Example:
/expand -5adds 5 blocks downwards.

💾 Advanced Export Modes
McTo3D offers versatile export options tailored to your hardware:
- Raw Mode: Exports pure geometry. Ideal for single-color prints or post-processing in Blender.
- Color Mode: Exports geometry with color data. Optimized for multi-material systems like Bambu Lab AMS or Prusa MMU, allowing for full-color 3D prints directly from the game.

- Adjust Height: (Optional) Use
/expand <value>to include the roof or basement if they weren't in your initial selection. - Export: Run the command
/export3d. - Locate File: Navigate to your
.minecraft/exportsfolder to find your generated file. - Slice & Print: Drag the file into your preferred slicer software.
⚙️ Compatibility
