The parts used are found in Hopetown (Valo system) and Red Mile (Porrima system)
You need to be about level 50 and have Class C piloting to see all the pieces.
I think most parts can be available at the large landing pad in your outpost (if you visited the shops) with the exception of the 2x3 Hopetech Cargo bay.

The full cost to build from scratch is about 1 million credits (cargo containers add up quick.) I did not keep exact track (sorry) as I had to do some design changes as I play tested it.

The cargo containers and fuel tanks are flexible. I used the smallest fuel tanks to keep the mass down and a player only needs about 800 fuel to cross the galaxy.

The cargo containers I used are assorted for the colors because they paintbrush will not change colors of the shipping containers. This also means you can go up or down in container sizes. Be warned going up in cargo containers will encounter "not enough landing thrust errors.)

The shielded cargo is low as only the two on the reactor are shield. The rear cargo containers are not shield, but they can be swapped with shielded ones at Red Mile.

The ship is exactly 80m long, which can be a nuisance in certain landing areas.

If it is too bothersome the design could go with three columns of containers rather than four. Reducing a section would bring it down to 75m and end this.
