[avogaado]

Probably the best 3x3 that currently exists

[Gekoloudios]

I still don't understand how a 0.3s 3x3 can be survival friendly...
this is insane

[DrJigglebones]

bro, I, what??? that's actually nuts how fast that is, kudos!

[Chizzyswiz]

Great door and tutorial. But I recommend going a bit slower

[bronzemercy]

Great explanation and great door! Good job!

[cheesedabber]

how compact and fast that is is actually crazy, well done!!!

[mattheus]

Aaayyy, New vídeo, finally! Btw, merry christmas

[NNNNNNNNNN-nnnnnnnnnn]

Let's Congrats for fixing the door without those sands!

[nugget]

think this is sick cause of how you could make another one flipped right next to it

[mechaboy]

I to watch the video 3 times to get it working
well worth the time, its so good

it was the fix that you did at 12:12 that I didn't do, so when I completed it the pistons weren't correct and the wrong stuff got pushed

[mechnic]

works in 1.21, but dang, fixing mistakes is very difficult if you dont understand how it works 😅 took me about an hour of studying every block i could see in the video and making sure mine matched it exactly before trying to open/close it, because that would break it again.
my suggestion to anyone struggling to get it working is to rewatch the entire video and make sure everything is in the correct position when the door is open. specifically, i saw that the block at 10:54 and the observer at 12:35 had both moved to the wrong spot which was causing the the top left side of the door to break.

holy shit you move so fast and I have no idea how you got any of this working but it is cool as hell

[UncleWisecatGains]

Wow, amazing explanation! That top rep i would say is the most difficult to understand for me, but i learned alot in this video, great job lum3nd0 👍

Just started a New survival world Just to make this door, has been less then 2 hours and I already have ALL the resources to do It

[Mr_Patate_Douce]

it seems that this doesn't work in survival 1.20.4, the note bloc becomes different when I activate the lever and the right part of the door doesn't activate, maybe I'm just stupid but I followed the tutorial step by step, I'm trying to do it in a multi server, maybe they forbid it, is there an alternative to the note block ?

[theoryan]

What size door are you doing next? Another 3x3, 4x4, or 5x5?

[mr_thug_penguin]

do u have any updates to ur 3x3 flush door... ur builds r insane but idk if it works on the newest version

[LebenDesFistus]

Seems to be broken in 1.21. I built it 3 times in survival and it brakes after opening and closing it a few times. Running on a vanilla fabric server.

[kreltex]

What mod do you use to select blocks and put them in their inventory?

Hello, just tried this is 1.20.4 and the very last step you did in the video, which was to fix a top left piston extending wrong still occurred after the last step. I don't know if I did this wrong but yea didn't work for me right now. Will delete if when I try the build again it's fixed. I gotta delete it all and restart now tho.
