![Tiny 5x5 (Full Flush) Pitch Cave Door [Tutorial | Explanation]](https://i.ytimg.com/vi/YnJCkIpDR2I/mqdefault.jpg "Tiny 5x5 (Full Flush) Pitch Cave Door [Tutorial | Explanation]
This is a Tiny 5x5 (Full Flush) Pitch Cave Door made by me. It is currently the Smallest Seamless 5x5 (Full Flush) Cave Door, at only 605 blocks.
I called it as a Pitch Cave Door based on the shape combination of the Pitch Door and the Cave Door.
This door is inspired by a post in r/qualityredstone. You can check out the post here:

Correction: The explanation from 44:50 to 47:22 is incorrect. As it turns out, the 1 tick repeater will not work in some locations/orientations. Change the 1 tick repeater to 2 ticks and it will fix the problem.
