Welcome to Nimbu's: Pocket Dimensions - a mod intended to add vanilla friendly customizable pocket dimensions that can be accessed from any location, and used for anything.
Required Dependencies:
Guide (Short):
Gateway Wand:
These pocket dimensions can be accessed from any location using a Gateway Wand.

The wand can be crafted with an echo shard and breeze rod as shown, and create a Gateway when right clicked.

Using the Gateway Wand on a created Gateway will destroy it.
Expansion Gem:
Pocket Dimensions are limited in size however - at least until Expansion Gems are crafted and used to open up an additional area of space.

Expansion Gems are crafted with a diamond, amethyst shard and ender pearl.
Holding the gem in the pocket dimension will make the borders fully visible, and can be right clicked on to be expanded.

[Note: Borders are not visible if shaders are on]
Dimension Customizer:
Lastly, the biome colours (colour of grass, leaves, water and sky) can be modified with the Dimension Customiser, as well as the material the Gateway itself is made out of (see the gallery for example uses).

This can be interacted with to freely modify the pocket dimension as the user pleases, and is made with 3 chiseled stone bricks, 2 cobblestone and an end crystal.
