From the update:
As promised a sneak peek of the Sci-Fi themed modules. These are just a few of the ones we have, but should give you an idea. There will be a double floor like in the first module with 2 different designs.
The door in this case is fixed, it has been made to be easily cut out. But, we have two more concepts we are working on to make a door that can be removed/opened and put back in place that we are studying.
