The Shipyards that goes with the Space Station (presented separately) comes in parts. If you don't have every ship, you don't need every berth. Download and print the berths you need individually. This file set is the Berth and Linking Walkway part for the Science Vessel space craft (the craft is downloaded separately). Each walkway Linking part goes together. Build it as long as you like. Use a Shipyards Linking Stand, included in this file set as well, to link up two strands of docking berths. The Science Vessel was down-scaled to 65.52/86.12/54 to fit well in its berth, or you can upscale the berth and whole shipyards. The choice is yours!
