800m (Estimation, based on size of the Sovereign Class)
Print orientation for Detail Plastic:
Despite the slightly lower surface quality, i really recommend ordering this in PA12. Detail Plastic is very brittle and this geometry is very fragile. Consider this before you chose Detail Plastic. You have been warned!
This is the drydock, the Enterprise-E is getting repaired in, at the end of "Star Trek: Nemesis". The dock has a structure in the middle that can dock with the Shuttlebay of a Sovereign Class, forming a physical connection and allowing personnel and material to switch between the ship and the dock comfortably. Although Ex-Astris-Scientia gives the length as some 900m, i made it only 800m long. I placed a 3D model of the Sovereign Class into it, and it looked much more like in the movie this way.
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
