This will be unpopular, but I would recommend getting an autoddsk Inventor eduational license, if you can, to learn the basics of parametric modeling. Build up general skills and then graduate to a FOSS solution like Freecad.
I would recommend finding broken gadgets/toys and home and reverse engineering replacement parts.
