A Better Realistic Multifloor Elevator

IceFlame22's Realistic Multifloor Elevator. World version: 1.21.5.

I made yet another elevator in Minecraft. This one is similar to my last design, but I have perfected it to be even more compact and efficient. One of the biggest improvements is that calling the elevator now does not start from the bottom or top, but from where the cabin is. It is also simply a cleaner design in general.

Dimensions: 17 by 17.
Elevator speed: 6.67 blocks/second.
The floors can be spaced any even number of blocks apart.
The elevator is singleplayer foolproof and spam-proof (In multiplayer, it breaks when two players call the elevator at the same time)

The world version is 1.21.5 but the build itself should be compatible with any version 1.16+, since I didn't use any features from beyond that point.

Credit to JL2579 again for the idea for the cabin lifting method. Go check out his YouTube channel!

**It's a year later and I finally decided to revisit this elevator in an attempt to make an even more compact version. In doing so I found one small, pretty insignificant bug and one significant bug. The insignificant bug: In the shorter 15-floor elevator only, some of the floors had a comparator set to compare more rather than subtract mode (coordinates were x=3, z=3). The taller 12-floor elevator did not have the same problem. The significant bug: For some reason, if you build the elevator north-south oriented instead of east-west oriented, the down-signal comparator that is supposed to be blocked when the elevator is going up does not get fully blocked. Don't ask me why; Minecraft's update ordering is weird. I updated the world download; it should be fixed now. Sorry if any of this caused confusion for someone. If you find any more bugs, please let me know.
