I came up with this for a project in class

Made in onshape, I provided a step file for the holder itself

I used a skate bearing (∅22mm) to get it to spin, HIGHLY recommend getting one, but if you don't have a bearing or it isn't the right size you could always increase the stub diameter to .3mm offset.

Also created a modular sd+microsd+usb holder, can fit into any of the containers

You could also get away with just printing the holder itself. Since the stub isn't on the holder, you can print it to be it's own standalone.
