Nintendo switch game card holder lid improvments

I am very excited about the model from RealBadDad. Thanks a lot for this.

But I noticed 2 points that I didn't quite like and I changed them here.

1. I reduced the lid height by 5mm. The game cardrigdes still fit in the case, but it simply takes up less space in the kids backpack.
2. I shortened the thread. As a result, the lid has no thread on the inside for the first few millimeters and can be attached first and then rotated. This will make it easier (even for children) to screw the blanket into the threads of the base.
