Launch a multiplayer game on your local server
One computer will act as a server, whilst other computer (as many as you want) will act as players.
On the server computer, launch minetest, and start a game where you will be hosting a server.
Create a new game first (in this case “jolin”)
Leave the Port field empty
Choose a name for your player (below we name it “sim”)

Join the game hosted on the server
On the computers acting as players, launch minetest, go on PLAY ONLINE and enter the IP address of the host server. Enter a name for the new player, leave the “Port” field empty and join the game.
On the computer acting as host server, you will be notified when a new player joins the game

Build something and export the 3D file
Use red wool blocks to build something of your choice. Beware that only red wool blocks can be exported for 3D printing.
Use the computer hosting the game to export the design. Go in front of the 3D object, open the communication window by typing “t” on your keyboard, and type “/exportblock”. Press ENTER
Wait until the game returns a message stating the export was successful
You will be able to find the .obj file in the directory “worlds” in your minetest folder on the computer hosting the game.
