Stackable external HDD mount

This accessory allows mounting one or several Seagate external hard disk drives to the Prusa Raspberry Pi Z-box with hex body and using it as a NAS.

Two pieces are used for attaching each disk drive. For attaching a disk to the main body, the files diskHolder_main/diskHolder_main_powerNotch should be printed. At least one of the printed files should be diskHolder_main_powerNotch which does not collide with the power cable for the Raspberry Pi. 

Any additional disks can be stacked below using two prints of the file diskHolder_stackable (picture 4) and connecting them below the main holder (pictures 5 and 6).
