12V PSU cover

Cover for popular 12V PSU found on most (china) budget 3D printers which measure 11cm x 5 cm (width x height). In contrast to most covers I found this one slips over the PSU case making it impossible to accidently get in contact with the main current wires. On one side it will snap into the perforated case on the other it will allow you to use a screw. Versions with holes for switch and plug may follow.
