Sci-fi Floor Airlock [Support-Free]

This is a simple floor airlock, designed to be plopped down anywhere to create a door that opens to space. It's designed to be flat/thin so it doesn't take up much room and minis can be placed on it. There's a solid closed version, an open version, and a door insert (if you prefer to use the closed version with a removable door). It's natively 4x4", which is pretty big. It prints great scaled down to .75 (which is 3x3") also.
