I have tried numerous world downloads and followed other sketchy tutorials to no avail.
I need/want to get an up/down elevator with a 'cabin' height of 3 so I can ride horses on it. A floor space of 3x3 is preferred, but 2x2 will suffice. It can use any method of movement (stacked pistons, slime blocks, etc...) to traverse up and down.
Any suggestions are appreciated, thanks!
