Former Tied Smallest 3x3 Piston Door (1.16+, with Tutorial)

Hello! quick upload to present to you a 3x3 that is 56 blocks, and it also has 8 air blocks, and it is very original compared to the one you may see using the basic top dpe layout. It took me 2 hours to make the original door, then 15 minutes to add as much air as possible. Thanks to HiHi for helping me with adding more air, here is their channel: https://www.youtube.com/channel/UC_5vZ5uVCxzm3ZzpfqPXImg On this note, I'll see you next time, hope you enjoyed, take care!
