IceFlame22's Newest Realistic Elevator. World version: 1.20.4.

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