For example, if you have a basement’s foundation laid out, you’ll need to dig this hole in the bottom of the basement’s foundation.
This is extremely important, so make sure that you’re positioned correctly before proceeding.
You may have to dig a temporary hole in order to get the correct angle needed to place a downward-facing sticky piston.
Leave the floating stone block that you placed in the last step empty.
Do not press the button yet—doing so will cause the elevator floor and base to fly into the sky, never to be seen again.
The placeholder should be as many blocks high as you want the elevator to be able to travel.
With the observer block’s face looking at you, the piston should be facing left.
At this point, when facing the back of the piston, you should see a three-wide row of stone blocks with a floating stone block above the right-most block in the row.
You can dress up the elevator with walls, doors, and so on.
