1. If you used Minecraft in the Design It! stage, you should now have a building made on a perfect square base. To turn that building into a file that can be printed on a 3D printer you will need to install a free program called Mineways.
Mineways is a program that can read the Minecraft environment and export a designated area into a three-dimensional file. Think of it as a bird’s eye view of your Minecraft world, where you have the power to draw a selection box around anything and then - zap! - turn that selection into a file that 3D printers can understand. Follow the quick-start guide from Mineways to get an easy, step-by-step understanding of how to make a model. Once you have a 3D file in .wrl or .stl format, you can upload your design to Shapeways and order a shipped print. Alternatively, if you have access to a 3D printer, consult your printer’s user guide or ask an expert to help you print off your design.

2. If you used Lego Digital Designer to make a building, you should now have a full 3D version of your finished model.
Press F7 or click on Building Guide Mode in order to view step-by-step instructions on how to create your building from scratch. Using your own lego, or the lego brick store, you can then create a physical version.
