Nintendo Switch Kickstand / MicroSD cover (Improved)

H3M4N's Switch cover is so close to complete. I took their design and added the following changes:

1. Scaled the design up (so the STL is in mm and won't need scaling during slicing).
2. added a slight bevel at the top (to help with rotation).
3. rounded the corners at the top, so it fits into place without modification.
4. added nubs at the bottom so it'll lock into place.

I lost my kickstand while traveling, and needed a replacement. This design works about as well as I remember the original working (flimsy plastic that could barely hold the switch up). Also, with the changes above, the kickstand can rotate in and out.
