This is a space station I built in the end. Getting all the little things took me about a week, and some of the wiring was a little frustrating, but I got it done. It has a working airlock, as well as some other little features inside the station. I made a failsafe way to teleport back if you fall out of the world, so don't worry. I chose the end because to me it looked a lot like space, so it was really the best candidate for where to place this build. Be sure to give feedback and clickity clack that diamond if you really like it. Enjoy!
