This mod allows you to explore your minecraft world freely while still having your own base whenever you need it.

How does it work?

• Place a house packer block on one corner of your structure and place a corner marker on the opposite corner of your structure. This way you can select an area up to 50x256x50 in size (where 256 is in the vertical coordinates).
• After that take a blueprint and stick it in the house packer (same way as a record in a jukebox).
• If you placed both blocks, the house packer will instantly spit out the schematic and your base will be packed into that tiny piece of paper. If you didn’t place them both, it will spit out the empty blueprint again. And that’s it.
• To unpack your house, place your house packer somewhere and unpack it.
