I had a few 2.5 inch drives to spare and bought a SATA to USB adapter cable
Dimension of SATA plug is 47x13mm
I could not find a perfect fit for an enclosure, so I designed it from scratch, making it as small and simple as possible. It can be used with or without the "back lid". The 4 side screws are used to keep the drive in place.
It prints with the SATA hole down. Supports for the bridges are included in the model, it breaks off easily after print. If you want to close the back opening, print the "lid" piece.
Support is built into the model, no need to add any. It is very simple to remove by peeling off by hand.
