So you don’t have to do it :)

Hopefully one efficient Zombie Spawner with a somewhat working baby zombie filter.

If you download this one, don’t go more than 16 blocks from spawner, if you do, it stops working (a 16 blocks circle centered on spawner) you can count out 11 blocks from the middle of the walls of the spawn building and your inside the 16 block circle.

Paste it to north and the water elevator is to the south, it needs 10 blocks down, 20 blocks up, 6 blocks front/north, 5 left/west and right/east and 15 behind/south of you. Look at picture there you stand when you paste it.

Don't forget you can “undo” and try again.

Want to use it as AFK grinder, lower hopper 1 block or just wait for entity cramming.

Have a great day and hope you enjoy the Zombie Spawner.
