The lightning bolt flash drive 'casing' can either fit a Sandisk Cruzer Facet or a Kingston Data Traveler SE9. There are two different designs to accommodate the size of each flash drive. No support is needed, but that is also dependent on how your printer can handle overhang. I glued the flash drive in the body with hot glue to secure it, I'm sure any glue would work. The model was printed with Verbatim PLA Yellow.
