Disk basement for Alien Jokey

I think the model published by Geoffro in 2014 - thing:383200 - is one of the best thing to print for those like me who loved the ALIEN original movie (first and only one).
But I wasn't satisfied by the basement, that don't reproduce the original disk basement that you can see in the movies, over it's mounted the Alien Jokey.
So I decided to make my own version of the disk to add it to the model, maybe it could be nice for someone else!
All the best from Italy!
