The intent per the repo was to give the Gotek a stealth look in the Amiga 1000 and 1010 drive when printing with a matching color. No cutting or case modification is needed. In fact with no USB key installed, the case looks stock at first. If you get a slim nano type drive, it is very stealth when in use.
