Swapped out my old crashed hard drive for an SSD in my iMac (the thick one). This adapter will do the trick. You unscrew the stuff off of the old drive and screw it into this adapter. See the photo for reference. The print will fit on even pretty small printers since the tray itself is smaller than a 3.5" drive.
This could work for other computers, but it's setup so the cables reach the SSD in an iMac.
