Go to the end dimension and make a bridge 128 blocks away from the main island.
At the end of the bridge make a 9x9 platform.
With a 3 block margin from the north and south part of the platform make a 2x3 hole with double chests and a 3x3 hole with hoppers connected to the chests.
Cover the hoppers with carpets.
Place slabs around the edge of the platform and make a roof two blocks high (to be able to stand up inside), with a hole over the hoppers 3x3.
Over the roof, place two layers of carpets covering all but a 1 block margin around the hole.
2 blocks over the margin without carpets, make a 5x5 ring. Make in total 13 rings with a 2 block space.
Over the last ring, make a 31x31 platform where the endermans will spawn, keeping the 3x3 hole where they'll fall.
Place 8 closed trapdoors around the falling hole.
Place 4 blocks in the middle of the hole and a chain on top of it.
Over the chain make the required platform to spawn a Endermite using ender pearls, when the Endermite spawns, use a label on it so it doesn't despawn. Push it into a minecart.
Break the blocks so the Endermite minecart drops on top of the chain.
Endermans will try to catch the Endermite and fall into the fall hole, they'll be at 1 hit.
