This is a decorative SD card holder that makes your cards look like snow capped mountains.
The remix is exactly the same as the original. The only change I have made is to fix the STL file so that it is the correct rotation. This should make it print correctly.
You can also fix the rotation in your slicer however novices may not be able to find this option or may be using a slicer that doesn't give that option (such as someone who wants to immediately upload to OctoPrint as far as I'm aware).
