You can put the measurement unit inside the measurement units.
In such measurements, it is convenient to make a pantry and carry it with you if necessary, or a portable home.
The mod will also add the following items:
End Crystal – needed to indicate the point of appearance in this dimension, that is, if you have built something inside and want to appear in a certain place.
Nether crystal – inside each dimension there are special connectors that allow you to transfer things from the dimension outward, with the help of this joke you can move this connector wherever it is convenient for you.

In fact, this is exactly the same mod for game versions 1.11.2, 1.12.2, and newer, the mod adds a special ore from which you can create a block of this dimension.
