what helped me was building gundam model kits, slowly and in a way that allows me to closely looking at the shapes of each parts and how they fit together, particularly the joints, and understand what each component is meant to do. Spent time looking at real machines or vehicles and try to find out what each parts do and how it moves. You just need to accumulate an internal library of individual components because they fit together like vocabularies in a paragraph.
