The USB stick case consists of two parts. A larger part (Fablab_USB_case_top.stl) for the cover of the USB stick and a smaller part for the USB stick. You can choose the smaller part either with a hole for a keyring (Fablab_USB_case_keyring.stl) or without a hole (Fablab_USB_case_noring.stl). After printing just use a glue for hard plastic to glue the two parts of the USB Micro stick into the 3D printed parts. The stick was created in close collaboration between several member of our FabLab in Winterthur, Switzerland for a design fair where we showcased the possibilities of our FabLab.
