End Crystal Quarry for Minecraft 1.12

Unique concept for a fast end dimension quarry. The least amount of effort (no roof, no bottom station, no trenches are needed) makes this the fastest way of creating voids in the end with the downside of not collecting any items. Works in Minecraft 1.11-1.12.2, for more information visit this video: https://youtu.be/e9kPFXK0zbA
