a somewhat compact (6x12x8) iron farm and when i was running it after making it it made about 4 blocks in ~10 minutes
just felt like making a sturdy sheet farm. it is a farm that is 7 blocks wide, 11 blocks long and 11 blocks tall
this is a dual purpose farm i decided to make it will probably be a bit slow at the start but it does work, you will have to turn it on after making it since to make the schematic ...
