Plastic Products and Mold Design

Hello, I'm writing here as a last resort ;) I think I searched all over Grabcad and unfortunately I didn't find anything, I'm starting to learn CAM programming, recently I've been working in a tool shop producing injection molds and stamping dies, I've mastered 2D and 2.5D programming, but 3D programming is a bit of a mess Our forms are simple, but they promise to be much more complicated next year, so I started looking for learning materials and came across interesting channels on YouTube, but the problem is that when I write to a given creator asking for the model he used in the film, there is silence, I managed to make a few I can achieve it, but it's not enough ;) I can model something myself, but it's better for me to learn from something that is real and in use, or manufactured and works somewhere :) I will give examples in the form of links to YT, what models I mean and would anyone be interested? Can I share some files?? maybe it will even happen that someone will have a model from a movie or channel, that will be very good :) or maybe someone knows a place where such models can be obtained or some keywords on how to search :) best regards and I will be grateful for your help
