There are plenty of awesome gadgets and toys available for Star Wars already. If 3D printing is your thing, you can also build your own. stonefx83 has shared a video that shows what it takes to 3D print a giant Millennium Falcon. It measures 500x170x700(mm) and weighs 3kg.
The 3D printer is controlled using Raspberry Pi 3 & Octoprint. Pretty impressive if you ask us. You can find the files to 3D print your own here.
