There are lots of Traveller sites on the web. Some offer adventure modules, some provide actual sector or character generators, and others involve ready made maps. As far as ship designs, Robert Pierce made a wonderful book of Traveller geomorphs a few years ago which can be found here https://travellerrpgblog.blogspot.com/ Look for the Geomorph 2.0 link on the right panel of his page. He has also had other people contribute to a growing line of ship designs. The only problem I see with them is that he designed them in an autocad program and published them in a pdf format. Eric Smith took all Pierce's pdfs, as well as adding some of his own, and converted them to pngs here https://gurpsland.no-ip.org/geomorphs/ These have a transparent background so they can be mixed and matched in a favorite graphics program, such as GIMP, Affinity Designer, Photoshop or Paint.net, to form an endless array of starship or station layouts. Both Robert's and Eric's work are for non-commercial use, I believe.
