This is the McKinley Drydock as seen on TNG. This drydock is especially build to "hold" Galaxy and Nebula Class Starships. In order to fit to the different ships the station can change its shape. The "arms" then can bend arround the ship. The filming model only had 7 arms (just 3 big ones), most probably to get the Enterprise Studio model in it including the rig that keeps it in place. This model has 8 arms and is in the configuration for Galaxy Class ships. Due to the fragile nature of the structure and because you might need to bend the arms a little when inserting a Galaxy Class miniature i highly recommend to buy this in any kind of Versatile Plastic or PA12. Detail Plastic might be too brittle for that.
If you need this in another material, size, or quantity, send me a message. I will try to make it as you need. Be sure to read my comments below my shop page
