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
