A little clip to hold your SD card adapter nearby when you're not using it.

I had initially intended this to hold the SD card square with the printbed, but I had made the tolerances too tight for the card to fit in as is. I think it actually works out better with the card at an angle, as it makes it easier to remove, but you could make it fit as intended by widening the slot by around 1Â mm.
Also, the fit onto the bed is very tight. If you want to make this a little easier, you could widen the gap between the legs by around 1Â mm and reducing the width of the clips by around 0.5Â mm each.
Printed as is, you may need to do some filing work on the legs (or sheer brute force) to get this onto the bed, but it shouldn't take too long.
The upside of the fit being so tight is that this doesn't rattle at all when the printer is in use.
Finally, to save material without impairing the function of this clip would be to halve the length of this clip as, when mounted at 45Â degrees, the SD card only protrudes into the slot about 50% of the length.
