Hello family,

I was wondering if there are any private/public trackers, or even websites of blueprints of things like car/ phones/, etc.? For example, bibliotik is a private tracker that has a lot of new books leaked. And how what.cd have the latest leaks of music. Well is there for blueprints trackers? I know there some websites, but there only show a pic or not a full assembly and steps. Any help well be great thanks !
