Realistic Elevator (with 15-floor version)

I made a new version of the world that contains a 15-floor copy of the original Realistic Elevator for those who would like a maximum-floor version. This is to avoid complications that viewers might have when copying floors. Adding new floors requires a lot of technical understanding of the elevator, which I did not explain thoroughly enough in my video, and I overlooked the severity of these complications before realizing that it would be easier to simply make a new world download. Also, copying any redstone device (at least with /clone; I'm not sure about structure blocks) that contains observers for some reason updates all the observers and activates them, meaning a bunch of pistons would have to be reset, which is hard to explain how/where to do without making another video. So, if you were interested in what the elevator would look like at 15 floors, here you go!
