How about a new and improved SD card holder for your key ring? Carry a spare card for your camera or to share photos with friends.
After 3 months in my pocket, my SD Fob finally snapped where the hook attaches to the sleeve. 123D Design wouldn't let me add a fillet around the complex geometry of the joint. Now comes along Fusion 360, and voilà! It now sports a huge fillet to last a lifetime!
Add a brim of 10-12 outlines to stick it onto the print bed.
Print several at once to give the plastic time to cool between layers. I reduced the print speed by 50% (to 30 mm / sec) for better quality.
Set minimum infill length to 0 in your slicer to put a little material in the tiny orientation key strips.
I sized this for my printer and ABS. You may scale it to taste in your slicer if necessary.
