Anybody who has ever played Garry's mod remembers the two standard maps: construct, and flatgrass. Since gm_construct was already made into a Minecraft map by Specals, I decided to make gm_flatgrass. I used standard crates in-game (in Garry's Mod) for measuring the size, because those looked the closest to 1 meter cubed. That means this map is scale 1:1!

How to use:
Step 1: Download this schematic to a place where you can find it,
Step 2: Make a Superflat world, with the top layer made of grass,
Step 3: Place the schematic anywhere you like using MCedit (I recommend close to the spawn), and you're done!
