Hi, This is my world download for my 99.9% Efficient Iron Farm Mark 2. When I say efficient I mean that when the game tries to spawn in a Golem it will be able to do so 99.9% of the time. This farm has 800 spawning locations compared to the often seen 504. Not as efficient as my 100% efficient design however much more survival friendly. Works for 1.8, 1.9 and 1.10.

Note, This world has 4 Iron Farms stacked on top of each other. If you intend to use this as a guide to building a single farm then please check back to the video. Stacking 4 farms vertically changes the design slightly in that you will need the slab bars which are on the top farm and the catch tray from the bottom one.
