Cassete Shaped External HD Case

If you had an old notebook that became obsolete, you probably tried to keep at least the hard drive.

There are many external case options for those 2.5 '' HD drives that convert the SATA connection to USB, turning the old drive into a portable mass storage device.

The design was made to fit into these cases with "rounded corners" , but if you have a different one, just edit the Sketchup file.
