I’ve modeled this motor: https://odriverobotics.com/shop/motor-and-encoder
Note that, as the grabcad description says - the external dimensions should be accurate, but I just made my best guess at the internals. Mass is correct (450g). If opened in SolidWorks, the assembly should also be correctly constrained (again, externally).
