My Thinkpad is missing the expresscard box entirely (it was broken, got thrown out) so this clip keeps the holder from falling into the case too far, makes it easy to pull out.

A good clever V2 edit would be to have a horizontal clip that bends into the palm rest hole next to it.

Still doesn't need supports, since the clip goes up. Can be annoying to accidentally knock it out with your hand this vertical orientation though.

Recommend you try shrinking it 1% or more if the cards are falling out (this STL isn't shrunk).

I guess PETg would be a better filament material for this but I don't have any right now.
