Not the most versatile. I made this to hold the Orico drive cases on the side of a ledge on my desk.

Holds two 2.5" SSD cases.  One is the USB-C, and the other is the micro USB one but should work with two USB-C cases.  Also holds one USB-C M.2 case.

I might improve this and made it more universal soon. 

Printed without supports on my printer before I dialed it in (that's why it looks bad).
