Slanted 3x3 Door! (New(?) Concept)

Hi! So about a week ago, I made this 3x3 door. But, it isn’t an ordinary 3x3 door. The door itself is slanted as it moves upward, giving it a weird but interesting look. I made a tutorial on my YouTube channel, and I’d love it if you took the time to maybe watch a little bit of it because I spent lots of my time and sanity working on this door, mainly because of a few bugs that took a long time to fix. You can also go to my plot /p h:2 Captain_Alessio to check it out for yourself, it’s at the very back slightly to the left. :D Thanks!
