![864 Block Fastest Possible 6x6 Seamless Cave Door [Explanation]](https://i.ytimg.com/vi/at6715jpA00/mqdefault.jpg "864 Block Fastest Possible 6x6 Seamless Cave Door [Explanation]
This is a small and fast 6x6 Seamless Cave Door by me and lum3nd0. It opens in 0.45s and closes in 0.45s, currently the fastest possible. For this speed, this door is also the smallest, at only 864 Blocks.
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.

This is a tinier 2x2 sticky piston-less door which is improved and built by me.
This is no longer going to be smallest since I have made a smaller one (again).
The sand used can be replaced with concrete powder in 1.12+. All droppers (except the bottom right-hand corner one) can be replaced with note blocks for the latest versions (I dont know the exact version).
