I didn't notice a way to post comments/questions to the classroom content so I'm doing that here. I watched the first snap fit video. Thank you for putting that together. I have one main question. Is the first Snap Fit use case for a permanent connection or is that supposed to be able to open and close at will? It seems like closing it would work fine, but with a 90 degree connection the other way, seems like I wouldn't be able to remove the lid once it was attached. Let me know if I'm missing something.
