It’s no secret that Han Solo made a bunch of modifications to the Millennium Falcon himself. To do that, he needed some serious tools. He probably used something like this Star Wars Millennium Falcon Multi-Tool Kit. It has everything you need to keep a spaceship running, whether you’re racing in the Kessel Run or evading Imperials. He and Chewy use this all of the time. Pretty sure I’ve even seen this in the movies. Nah. Probably not.
