Server address:

The Fab Lab hosts an open-source Minecraft server for free use. It is a [no PVP] collaboration-oriented creative mode and [PVE] survival server intended to help players who want to learn how to design and print in 3D, experiment with Redstone and build command-block-driven digital story experiences.

How to join a Minecraft server We have lots of camps on Minecraft! Run Minecraft in an older version mode for our servers

Operations and Building Guides

Our server has some pretty powerful tools – learn to use them!

Minecraft Creative Mode Basics

Start With Learning to Build Better

Protect Your Creations with WorldGuard

You can prevent other players from being able to modify or destroy your creations if you protect them.


Use the WOODEN AXE to make a cuboid selection like the above.

  1. Left click lower corner (first point)
  2. Select the top corner by typing
    /up 1 
    and right click the glass block (second point)
  3. To protect create and protect the region type
    /region define [region_name] [your_minecraft_name]

Avoid commonly-used names like ‘house’ or ‘castle’ because someone will have already used it. Don’t use spaces in your names! Swap out ‘define’ with addmember to add a friend to edit your region. Examples:

/region define Jeff_mansion Geph
/region addmember Jeff_mansion fablab_razmataz

Teleport to Your Regions

  1. Setting a teleport point by typing
    /region flag [region_name] teleport here
  2. Teleport to your region then by typing
    /region tp [region_name]

Use /spawn to teleport home to the spawn.

Adjust Members on Your Regions

In some cases you may want to add new people or remove someone from your protected region. You can do that with:

/rg addowner [region_name] [user_name] or /rg removeowner [user_name]
/rg addmember [region_name] [user_name] or /rg removemember [user_name]

Owners have permission to add and remove members.
