Redbox Nintendo Switch Case Remix

## Summary
Using [jandajanda's base](https://www.thingiverse.com/thing:6827522), this switch case version improves in a few areas that I found helpful/needed.

1. The cart slot has been slightly narrowed to fit a switch game cart better. The original model was a bit too loose for my liking.
2. The dimensions of the case are now closer to an actual Redbox DVD case in size.
3. The shape of the case is now more uniform on the top and bottom for easier printing.
4. I uploaded a multi-color ready 3mf project file that was made in Bambu Studio.**

In case you want to print from scratch or don't care about having the Redbox logo/arrows on top, here are the print settings I used for minimal material use while still getting a god quality result.
